• Upgrading VSIX extensions from VS2012 to VS2013

  - by Tarun Arora [Microsoft MVP]

  Originally posted on: http://geekswithblogs.net/TarunArora/archive/2013/06/27/upgrading-vsix-extensions-from-vs2012-to-vs2013.aspx  As consumers of your Visual Studio extensions start to move over to VS 2013, you will have to upgrade the Visual Studio extensions you build for Visual Studio 2012 to Visual Studio 2013 and republish to the Visual Studio extension gallery. Failing which, it will not be possible for your consumers to install and use your extensions on Visual Studio 2013.   Objective In this blog post, I’ll show you how simple it is to upgrade your Visual Studio 2012 extension to Visual Studio 2013. There aren’t any reported breaking changes between VS 2012 SDK and VS 2013 SDK, the upgrade usually involves, rebuilding the extension against VS 2013 SDK and updating the vsix manifest file.              Walkthrough Download the Visual Studio 2013 SDK - You will need to download the Visual Studio 2013 SDK in order to open up the Visual Studio extension project in Visual Studio 2013. The SDK can be downloaded from here. Install the SDK before you proceed.                2. Once the VS 2013 SDK has been installed, open up your package project. For the purposes of this blog post, I’ll open up the Avanade Extension – Software Inventory in Visual Studio 2013. You will notice that Visual Studio doesn’t load the project but let’s you know that the project needs to be Migrated.                  3. Right click the project and choose the option ‘Reload Project’ from the Context Menu.                  4. Choosing the Reload Project option brings up an upgrade window, telling you that the upgrade is a one way only upgrade i.e. the project will be changed to work with Visual Studio 2013 and you will not be able to open the project up in Visual Studio 2012. My recommendation would be to create a Visual Studio 2013 branch and upgrading the project in that branch only, so if you need to go back to Visual Studio 2012 project at some point, you have a handy reference in a separate branch.             5. Upon clicking Ok, the project is updated. See below, the following changes are made at the time of upgrade,           - The runtime version is updated in the Resources.Designer.cs file                      - The Minimum version of Visual Studio in the package project file is changed from 11.0 to 12.0                    6. Reference VS 2013 dll’s rather than VS 2012 dll’s. So reference Microsoft.TeamFoundation.Client.dll and Microsoft.TeamFoundation.Controls.dll from C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0 and C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v4.5. If you have any other API references, then change the references to point to VS 2013 instead of VS 2012.                          7. Rebuild your solution to ensure there are no breaking changes. Success!                8. Update VSIX Manifest file (the file source.extnsion.vsixmanifest contains the meta data for your VSIX).          - Update the Install Targets from 11.0 to 12.0. This basically enforces that the extension can be installed on Visual Studio 2013 version of Visual Studio.                         - Update the Dependencies from Visual Studio MPF 11.0 to Visual Studio MPF 12.0              9. Rebuild the solution and open up the bin folder for the Package project and look for the file *.vsix file [Microsoft Visual Studio Extension].         - This is basically the installer for your extension.                 - Double click the installer to launch the installer wizard. Viola! You can see the package installation wizard opens up and gives you the option to install the extension for Visual Studio 2013.                    - Click Install to Continue                    - Note – If you run into the exception “23/06/2013 10:42:18 - Install Error : Microsoft.VisualStudio.ExtensionManager.InstallByMsiException: The InstalledByMSI element in extension Avanade Extensions cannot be 'true' when installing an extension through the Extensions and Updates Installer.  The element can only be 'true' when an MSI lays down the extension manifest file.” Ensure you have the option “This VSIX is installed by Windows Installer” unchecked in the Install Targets tab.        10. Verifying that the extension has installed correctly.           - Open Extension Manager and verify that the installed extension shows up in the extension manager “list of installed VSIX”.                      11. First Look at the updated Extension                         - The links have now been moved to the context menu, so to see the navigation links, you’ll have to right click on the icon and select the option from the context menu.                                        Note – The Avanade Extension being used in the demo has been developed by Utkarsh and Tarun. The Software Inventory Extension for Visual Studio 2012…  allows you to see the list of Software installed on the hosted build server right from with in Visual Studio,  the extension also allows you to export this list to excel. More details on how this has been implemented can be found here.   I hope you found this useful. In case you have any questions or feedback, feel free to reach out on Visual Studio extensibility MSDN forums or via Microsoft Visual Studio feedback forum.

• Writing an ASP.Net Web based TFS Client

  - by Glav

  So one of the things I needed to do was write an ASP.Net MVC based application for our senior execs to manage a set of arbitrary attributes against stories, bugs etc to be able to attribute whether the item was related to Research and Development, and if so, what kind. We are using TFS Azure and don’t have the option of custom templates. I have decided on using a string based field within the template that is not very visible and which we don’t use to write a small set of custom which will determine the research and development association. However, this string munging on the field is not very user friendly so we need a simple tool that can display attributes against items in a simple dropdown list or something similar. Enter a custom web app that accesses our TFS items in Azure (Note: We are also using Visual Studio 2012) Now TFS Azure uses your Live ID and it is not really possible to easily do this in a server based app where no interaction is available. Even if you capture the Live ID credentials yourself and try to submit them to TFS Azure, it wont work. Bottom line is that it is not straightforward nor obvious what you have to do. In fact, it is a real pain to find and there are some answers out there which don’t appear to be answers at all given they didn’t work in my scenario. So for anyone else who wants to do this, here is a simple breakdown on what you have to do: Go here and get the “TFS Service Credential Viewer”. Install it, run it and connect to your TFS instance in azure and create a service account. Note the username and password exactly as it presents it to you. This is the magic identity that will allow unattended, programmatic access. Without this step, don’t bother trying to do anything else. In your MVC app, reference the following assemblies from “C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ReferenceAssemblies\v2.0”: Microsoft.TeamFoundation.Client.dll Microsoft.TeamFoundation.Common.dll Microsoft.TeamFoundation.VersionControl.Client.dll Microsoft.TeamFoundation.VersionControl.Common.dll Microsoft.TeamFoundation.WorkItemTracking.Client.DataStoreLoader.dll Microsoft.TeamFoundation.WorkItemTracking.Client.dll Microsoft.TeamFoundation.WorkItemTracking.Common.dll If hosting this in Internet Information Server, for the application pool this app runs under, you will need to enable 32 Bit support. You also have to allow the TFS client assemblies to store a cache of files on your system. If you don’t do this, you will authenticate fine, but then get an exception saying that it is unable to access the cache at some directory path when you query work items. You can set this up by adding the following to your web.config, in the <appSettings> element as shown below: <appSettings> <!-- Add reference to TFS Client Cache --> <add key="WorkItemTrackingCacheRoot" value="C:\windows\temp" /> </appSettings> With all that in place, you can write the following code: var token = new Microsoft.TeamFoundation.Client.SimpleWebTokenCredential("{you-service-account-name", "{your-service-acct-password}"); var clientCreds = new Microsoft.TeamFoundation.Client.TfsClientCredentials(token); var currentCollection = new TfsTeamProjectCollection(new Uri(“https://{yourdomain}.visualstudio.com/defaultcollection”), clientCreds); TfsConfigurationServercurrentCollection.EnsureAuthenticated(); In the above code, not the URL contains the “defaultcollection” at the end of the URL. Obviously replace {yourdomain} with whatever is defined for your TFS in Azure instance. In addition, make sure the service user account and password that was generated in the first step is substituted in here. Note: If something is not right, the “EnsureAuthenticated()” call will throw an exception with the message being you are not authorised. If you forget the “defaultcollection” on the URL, it will still fail but with a message saying you are not authorised. That is, a similar but different exception message. And that is it. You can then query the collection using something like: var service = currentCollection.GetService<WorkItemStore>(); var proj = service.Projects[0]; var allQueries = proj.StoredQueries; for (int qcnt = 0; qcnt < allQueries.Count; qcnt++) {     var query = allQueries[qcnt];     var queryDesc = string.format(“Query found named: {0}”,query.Name); } You get the idea. If you search around, you will find references to the ServiceIdentityCredentialProvider which is referenced in this article. I had no luck with this method and it all looked too hard since it required an extra KB article and other magic sauce. So I hope that helps. This article certainly would have helped me save a boat load of time and frustration.

• Configuring Application/User Settings in WPF the easy way.

  - by mbcrump

  In this tutorial, we are going to configure the application/user settings in a WPF application the easy way. Most example that I’ve seen on the net involve the ConfigurationManager class and involve creating your own XML file from scratch. I am going to show you a easier way to do it. (in my humble opinion) First, the definitions: User Setting – is designed to be something specific to the user. For example, one user may have a requirement to see certain stocks, news articles or local weather. This can be set at run-time. Application Setting – is designed to store information such as a database connection string. These settings are read-only at run-time. 1) Lets create a new WPF Project and play with a few settings. Once you are inside VS, then paste the following code snippet inside the <Grid> tags. <Grid> <TextBox Height="23" HorizontalAlignment="Left" Margin="12,11,0,0" Name="textBox1" VerticalAlignment="Top" Width="285" Grid.ColumnSpan="2" /> <Button Content="Set Title" Name="button2" Click="button2_Click" Margin="108,40,96,114" /> <TextBlock Height="23" Name="textBlock1" Text="TextBlock" VerticalAlignment="Bottom" Width="377" /> </Grid> Basically, its just a Textbox, Button and TextBlock. The main Window should look like the following:   2) Now we are going to setup our Configuration Settings. Look in the Solution Explorer and double click on the Settings.settings file. Make sure that your settings file looks just like mine included below:   What just happened was the designer created an XML file and created the Settings.Designer.cs file which looks like this: //------------------------------------------------------------------------------ // <auto-generated> // This code was generated by a tool. // Runtime Version:4.0.30319.1 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------ namespace WPFExam.Properties { [global::System.Runtime.CompilerServices.CompilerGeneratedAttribute()] [global::System.CodeDom.Compiler.GeneratedCodeAttribute("Microsoft.VisualStudio.Editors.SettingsDesigner.SettingsSingleFileGenerator", "10.0.0.0")] internal sealed partial class Settings : global::System.Configuration.ApplicationSettingsBase { private static Settings defaultInstance = ((Settings)(global::System.Configuration.ApplicationSettingsBase.Synchronized(new Settings()))); public static Settings Default { get { return defaultInstance; } } [global::System.Configuration.UserScopedSettingAttribute()] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Configuration.DefaultSettingValueAttribute("ApplicationName")] public string ApplicationName { get { return ((string)(this["ApplicationName"])); } set { this["ApplicationName"] = value; } } [global::System.Configuration.ApplicationScopedSettingAttribute()] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Configuration.DefaultSettingValueAttribute("SQL_SRV342")] public string DatabaseServerName { get { return ((string)(this["DatabaseServerName"])); } } } } The XML File is named app.config and looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="WPFExam.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> </sectionGroup> <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="WPFExam.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </sectionGroup> </configSections> <userSettings> <WPFExam.Properties.Settings> <setting name="ApplicationName" serializeAs="String"> <value>ApplicationName</value> </setting> </WPFExam.Properties.Settings> </userSettings> <applicationSettings> <WPFExam.Properties.Settings> <setting name="DatabaseServerName" serializeAs="String"> <value>SQL_SRV342</value> </setting> </WPFExam.Properties.Settings> </applicationSettings> </configuration> 3) The only left now is the code behind the button. Double click the button and replace the MainWindow() method with the following code snippet. public MainWindow() { InitializeComponent(); this.Title = Properties.Settings.Default.ApplicationName; textBox1.Text = Properties.Settings.Default.ApplicationName; textBlock1.Text = Properties.Settings.Default.DatabaseServerName; } private void button2_Click(object sender, RoutedEventArgs e) { Properties.Settings.Default.ApplicationName = textBox1.Text.ToString(); Properties.Settings.Default.Save(); } Run the application and type something in the textbox and hit the Set Title button. Now, restart the application and you should see the text that you entered earlier.   If you look at the button2 click event, you will see that it was actually 2 lines of codes to save to the configuration file. I hope this helps, for more information consult MSDN.

• What are some concise and comprehensive introductory guide to unit testing for a self-taught programmer [closed]

  - by Superbest

  I don't have much formal training in programming and I have learned most things by looking up solutions on the internet to practical problems I have. There are some areas which I think would be valuable to learn, but which ended up both being difficult to learn and easy to avoid learning for a self-taught programmer. Unit testing is one of them. Specifically, I am interested in tests in and for C#/.NET applications using Microsoft.VisualStudio.TestTools in Visual Studio 2010 and/or 2012, but I really want a good introduction to the principles so language and IDE shouldn't matter much. At this time I'm interested in relatively trivial tests for small or medium sized programs (development time of weeks or months and mostly just myself developing). I don't necessarily intend to do test-driven development (I am aware that some say unit testing alone is supposed to be for developing features in TDD, and not an assurance that there are no bugs in the software, but unit testing is often the only kind of testing for which I have resources). I have found this tutorial which I feel gave me a decent idea of what unit tests and TDD looks like, but in trying to apply these ideas to my own projects, I often get confused by questions I can't answer and don't know how to answer, such as: What parts of my application and what sorts of things aren't necessarily worth testing? How fine grained should my tests be? Should they test every method and property separately, or work with a larger scope? What is a good naming convention for test methods? (since apparently the name of the method is the only way I will be able to tell from a glance at the test results table what works in my program and what doesn't) Is it bad to have many asserts in one test method? Since apparently VS2012 reports only that "an Assert.IsTrue failed within method MyTestMethod", and if MyTestMethod has 10 Assert.IsTrue statements, it will be irritating to figure out why a test is failing. If a lot of the functionality deals with writing and reading data to/from the disk in a not-exactly trivial fashion, how do I test that? If I provide a bunch of files as input by placing them in the program's directory, do I have to copy those files to the test project's bin/Debug folder now? If my program works with a large body of data and execution takes minutes or more, should my tests have it do the whole use all of the real data, a subset of it, or simulated data? If latter, how do I decide on the subset or how to simulate? Closely related to the previous point, if a class is such that its main operation happens in a state that is arrived to by the program after some involved operations (say, a class makes calculations on data derived from a few thousands of lines of code analyzing some raw data) how do I test just that class without inevitably ending up testing that class and all the other code that brings it to that state along with it? In general, what kind of approach should I use for test initialization? (hopefully that is the correct term, I mean preparing classes for testing by filling them in with appropriate data) How do I deal with private members? Do I just suck it up and assume that "not public = shouldn't be tested"? I have seen people suggest using private accessors and reflection, but these feel like clumsy and unsuited for regular use. Are these even good ideas? Is there anything like design patterns concerning testing specifically? I guess the main themes in what I'd like to learn more about are, (1) what are the overarching principles that should be followed (or at least considered) in every testing effort and (2) what are popular rules of thumb for writing tests. For example, at one point I recall hearing from someone that if a method is longer than 200 lines, it should be refactored - not a universally correct rule, but it has been quite helpful since I'd otherwise happily put hundreds of lines in single methods and then wonder why my code is so hard to read. Similarly I've found ReSharpers suggestions on member naming style and other things to be quite helpful in keeping my codebases sane. I see many resources both online and in print that talk about testing in the context of large applications (years of work, 10s of people or more). However, because I've never worked on such large projects, this context is very unfamiliar to me and makes the material difficult to follow and relate to my real world problems. Speaking of software development in general, advice given with the assumptions of large projects isn't always straightforward to apply to my own, smaller endeavors. Summary So my question is: What are some resources to learn about unit testing, for a hobbyist, self-taught programmer without much formal training? Ideally, I'm looking for a short and simple "bible of unit testing" which I can commit to memory, and then apply systematically by repeatedly asking myself "is this test following the bible of testing closely enough?" and then amending discrepancies if it doesn't.

• Telerik Object reference not set to an instance of an object

  Hi, I have a main form which contains multiple worker threads. These threads raise events which update Telerik controls on the main form.

• WebClient error when using a thread in .NET

  - by Kiranu

  I'm having a very weird error using the WebClient class in .NET 4. The app simply downloads some files off the internet and provides output on a textbox (the GUI is WPF). The method that does this is the following: void DownloadFiles(object files) { fileL = (List<string>) files; foreach (string url in fileL) { byte[] data; using (System.Net.WebClient k = new WebClient()) { data = k.DownloadData(url); } //Bunch of irrelevant code goes here... } } (I added the using while trying to divine [yes I'm that desperate/ignorant] a solution, the problem happens even if the webclient is declared and initialized outside the foreach loop) Now the problem appears only when I'm executing this method on a thread separate from the WPF UI main thread. If it is executed on the UI thread then it works perfectly. When a new thread is created with: Thread t = new Thread(DownloadFiles); t.Start(files); The first time the code goes into the loop it will work, but when its the second pass inside the loop, I will always receive a TargetParameterCountException. I can't make any sense of this error. Any help is very much appreciated. EDIT Here are the Exception Details: Exception.Message = "Parameter count mismatch."

  I'm having a very weird error using the WebClient class in .NET 4. The app simply downloads some files off the internet and provides output on a textbox (the GUI is WPF). The method that does this is the following: void DownloadFiles(object files) { fileL = (List<string>) files; foreach (string url in fileL) { byte[] data; using (System.Net.WebClient k = new WebClient()) { data = k.DownloadData(url); } //Bunch of irrelevant code goes here... } } (I added the using while trying to divine [yes I'm that desperate/ignorant] a solution, the problem happens even if the webclient is declared and initialized outside the foreach loop) Now the problem appears only when I'm executing this method on a thread separate from the WPF UI main thread. If it is executed on the UI thread then it works perfectly. When a new thread is created with: Thread t = new Thread(DownloadFiles); t.Start(files); The first time the code goes into the loop it will work, but when its the second pass inside the loop, I will always receive a TargetParameterCountException. I can't make any sense of this error. Any help is very much appreciated. EDIT Here are the Exception Details: Exception.Message = "Parameter count mismatch." Exception.InnerException = null Exception.Source = " mscorlib" The StackTrace follows: at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) at System.Delegate.DynamicInvokeImpl(Object[] args) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler) at System.Windows.Threading.DispatcherOperation.InvokeImpl() at System.Windows.Threading.DispatcherOperation.InvokeInSecurityContext(Object state) at System.Threading.ExecutionContext.runTryCode(Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Windows.Threading.DispatcherOperation.Invoke() at System.Windows.Threading.Dispatcher.ProcessQueue() at System.Windows.Threading.Dispatcher.WndProcHook(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler) at System.Windows.Threading.Dispatcher.InvokeImpl(DispatcherPriority priority, TimeSpan timeout, Delegate method, Object args, Int32 numArgs) at MS.Win32.HwndSubclass.SubclassWndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam) at MS.Win32.UnsafeNativeMethods.DispatchMessage(MSG& msg) at System.Windows.Threading.Dispatcher.PushFrameImpl(DispatcherFrame frame) at System.Windows.Threading.Dispatcher.PushFrame(DispatcherFrame frame) at System.Windows.Threading.Dispatcher.Run() at System.Windows.Application.RunDispatcher(Object ignore) at System.Windows.Application.RunInternal(Window window) at System.Windows.Application.Run(Window window) at System.Windows.Application.Run() at FileDownloader.App.Main() in d:\mis documentos\visual studio 2010\Projects\OneMangaDownloader\FileDownloader\obj\x86\Debug\App.g.cs:line 0 at System.AppDomain._nExecuteAssembly(RuntimeAssembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()

• Exception using SQLiteDataReader

  I'm making a Custom SQLite Wrapper. This is meant to allow a presistent connection to a database. However, I receive an exception when calling this function twice. public Boolean DatabaseConnected(string databasePath) { bool exists = false; if (ConnectionOpen()) { this.Command.CommandText = string.Format(DATABASE_QUERY); using (reader = this.Command.ExecuteReader()) { while (reader.Read()) { if (string.Compare(reader[FILE_NAME_COL_HEADER].ToString(), databasePath, true) == 0) { exists = true; break; } } reader.Close(); } } return exists; } I use the above function to check if the database is currently open before executing a command or trying to open a database. The first time I execute the function, it executes with no issue. After that the reader = this.Command.ExecuteReader() throws an exception Object reference not set to an instance of an object.

• error working with wsdl files in visual studio 2008

  Hi. I got a wsdl file in email. At first I didn't know how to use it. I've simply saved the file to my disk. Opened visual studio...added a service reference...provided path to file, and service was discovered. I opened the object browser to see the types and methods that got imported. I figure anything that ends with the name 'Client' is a good place to start using the web service. I've tried using a simple method to get data but it has run into and expception. Need help in resolving it.

• Properly Establishing an ApplicationEndpoint in UCMA 3.0

  - by user570720

  I've been struggling with getting an application endpoint working on UCMA 3.0. I am trying to run an application on a server separate from the Lync server which uses a registered ApplicationEndpoint to monitor presence and act as a bot which can send other users messages. I used to have my code working with a UserEndpoint (which was fine for monitoring presence), but did not have the capabilities to send IMs to other Lync users. After searching the web, I'm finally at the point where I'm getting this error when running my code: System.ArgumentException was unhandled Message=An ApplicationEndpoint can be registered only if proxy and Multual Tls have been specified. Source=Microsoft.Rtc.Collaboration StackTrace: at Microsoft.Rtc.Collaboration.ApplicationEndpoint..ctor(CollaborationPlatform platform, ApplicationEndpointSettings settings) at Waldo.endpointHelper.CreateApplicationEndpoint(ApplicationEndpointSettings applicationEndpointSettings) in C:\Users\l1m5\Desktop\waldoproject\trunk\WaldoSoln\waldoGrabPresence\endpointHelper.cs:line 117 at Waldo.endpointHelper.CreateEstablishedApplicationEndpoint(String endpointFriendlyName) in C:\Users\l1m5\Desktop\waldoproject\trunk\WaldoSoln\waldoGrabPresence\endpointHelper.cs:line 228 at Waldo.waldoGrabPresence.Run() in C:\Users\l1m5\Desktop\waldoproject\trunk\WaldoSoln\waldoGrabPresence\waldoGrabPresence.cs:line 60 at Waldo.waldoGrabPresence.Main(String[] args) in C:\Users\l1m5\Desktop\waldoproject\trunk\WaldoSoln\waldoGrabPresence\waldoGrabPresence.cs:line 42 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException: After some searching, I followed the instructions here: http://blogs.claritycon.com/blogs/michael_greenlee/archive/2009/03/21/installing-a-certificate-for-ucma-v2-0-applications.aspx to import a certificate onto the server that I'm trying to run the application on, but to no avail. So at this point, I think that there must be something wrong with how I'm setting up the ApplicationEndpointSettings, CollaberationPlatform or ApplicationEndpoint objects. Here's how I'm doing it: ApplicationEndpointSettings settings = new ApplicationEndpointSettings(_ownerURIPrompt, _serverFQDNPrompt, _trustedPortPrompt); ServerPlatformSettings settings = new ServerPlatformSettings(null, _serverFQDNPrompt, _trustedPortPrompt, _trustedApplicationGRUU); _collabPlatform = new CollaborationPlatform(settings); _applicationEndpoint = new ApplicationEndpoint(_collabPlatform, applicationEndpointSettings); Does anyone see any problems with what I'm doing? Or, better yet, does anyone know of a blog that walks you through establishing an application endpoint in the situation I'm in? I work really well with tutorials or samples, but have not found one that seems to accomplish what I'm trying to do. Thanks for the help!

• Exception showing a erroneous web page in a WPF frame

  - by H4mm3rHead

  I have a small application where i need to navigate to an url, I use this method to get the Frame: public override System.Windows.UIElement GetPage(System.Windows.UIElement container) { XmlDocument doc = new XmlDocument(); doc.Load(Location); string webSiteUrl = doc.SelectSingleNode("website").InnerText; Frame newFrame = new Frame(); if (!webSiteUrl.StartsWith("http://")) { webSiteUrl = "http://" + webSiteUrl; } newFrame.Source = new Uri(webSiteUrl); return newFrame; } My problem is now that the page im trying to show generates a error (or so i think), when i load the page in a browser it never fully loads, keeps saying "loading1 element" in the load bar and the green progress line (IE 8) keeps showing.

• C++ snippet support in visual studio?

  - by Jeremy Bell

  I'm writing code in native C++ (not C++/CLR). I know that there is no built-in support for C++ with regards to the snippet manager and snipper picker interfaces, however I found a utility called "snippy" which supposedly can generate C++ snippets. Here is a c++ snippet that the program generated: <?xml version="1.0" encoding="utf-8"?> <CodeSnippets xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet"> <CodeSnippet Format="1.0.0"> <Header> <Title>MySnippet</Title> <Shortcut>MySnippet</Shortcut> <Description>Just a test snippet</Description> <Author>Me</Author> <SnippetTypes> <SnippetType>Expansion</SnippetType> </SnippetTypes> </Header> <Snippet> <Declarations> <Literal Editable="true"> <ID>literal1</ID> <ToolTip>just a placeholder</ToolTip> <Default> </Default> <Function> </Function> </Literal> </Declarations> <Code Language="cpp"><![CDATA[cout << "$literal1$" << std::endl;]]></Code> </Snippet> </CodeSnippet> </CodeSnippets> If there is support in visual C++, even in a limited capacity, for C++ snippets, how do I add them to my environment, and what are the limitations? All I need is support for basic expansion snippets that I can invoke by typing a shortcut and hitting tab, and which supports basic literals that I can tab through (basically, if it supports the above snippet, I'm good). If this can't be done, are there any free add-ons or extensions to visual studio that support snippets for C++? I'm using both visual studio 2010 and 2008, but I mostly write code in 2010 right now.

• Notes on implementing Visual Studio 2010 Navigate To

  - by cyberycon

  One of the many neat functions added to Visual Studio in VS 2010 was the Navigate To feature. You can find it by clicking Edit, Navigate To, or by using the keyboard shortcut Ctrl, (yes, that's control plus the comma key). This pops up the Navigate To dialog that looks like this: As you type, Navigate To starts searching through a number of different search providers for your term. The entries in the list change as you type, with most providers doing some kind of fuzzy or at least substring matching. If you have C#, C++ or Visual Basic projects in your solution, all symbols defined in those projects are searched. There's also a file search provider, which displays all matching filenames from projects in the current solution as well. And, if you have a Visual Studio package of your own, you can implement a provider too. Micro Focus (where I work) provide the Visual COBOL language inside Visual Studio (http://visualstudiogallery.msdn.microsoft.com/ef9bc810-c133-4581-9429-b01420a9ea40 ), and we wanted to provide this functionality too. This post provides some notes on the things I discovered mainly through trial and error, but also with some kind help from devs inside Microsoft. The expectation of Navigate To is that it searches across the whole solution, not just the current project. So in our case, we wanted to search for all COBOL symbols inside all of our Visual COBOL projects inside the solution. So first of all, here's the Microsoft documentation on Navigate To: http://msdn.microsoft.com/en-us/library/ee844862.aspx . It's the reference information on the Microsoft.VisualStudio.Language.NavigateTo.Interfaces Namespace, and it lists all the interfaces you will need to implement to create your own Navigate To provider. Navigate To uses Visual Studio's latest mechanism for integrating external functionality and services, Managed Extensibility Framework (MEF). MEF components don't require any registration with COM or any other registry entries to be found by Visual Studio. Visual Studio looks in several well-known locations for manifest files (extension.vsixmanifest). It then uses reflection to scan for MEF attributes on classes in the assembly to determine which functionality the assembly provides. MEF itself is actually part of the .NET framework, and you can learn more about it here: http://mef.codeplex.com/. To get started with Visual Studio and MEF you could do worse than look at some of the editor examples on the VSX page http://archive.msdn.microsoft.com/vsx . I've also written a small application to help with switching between development and production MEF assemblies, which you can find on Codeproject: http://www.codeproject.com/KB/miscctrl/MEF_Switch.aspx. The Navigate To interfaces Back to Navigate To, and summarizing the MSDN reference documentation, you need to implement the following interfaces: INavigateToItemProviderFactoryThis is Visual Studio's entry point to your Navigate To implementation, and you must decorate your implementation with the following MEF export attribute: [Export(typeof(INavigateToItemProviderFactory))]  INavigateToItemProvider Your INavigateToItemProviderFactory needs to return your implementation of INavigateToItemProvider. This class implements StartSearch() and StopSearch(). StartSearch() is the guts of your provider, and we'll come back to it in a minute. This object also needs to implement IDisposeable(). INavigateToItemDisplayFactory Your INavigateToItemProvider hands back NavigateToItems to the NavigateTo framework. But to give you good control over what appears in the NavigateTo dialog box, these items will be handed back to your INavigateToItemDisplayFactory, which must create objects implementing INavigateToItemDisplay  INavigateToItemDisplay Each of these objects represents one result in the Navigate To dialog box. As well as providing the description and name of the item, this object also has a NavigateTo() method that should be capable of displaying the item in an editor when invoked. Carrying out the search The lifecycle of your INavigateToItemProvider is the same as that of the Navigate To dialog. This dialog is modal, which makes your implementation a little easier because you know that the user can't be changing things in editors and the IDE while this dialog is up. But the Navigate To dialog DOES NOT run on the main UI thread of the IDE – so you need to be aware of that if you want to interact with editors or other parts of the IDE UI. When the user invokes the Navigate To dialog, your INavigateToItemProvider gets sent a TryCreateNavigateToItemProvider() message. Instantiate your INavigateToItemProvider and hand this back. The sequence diagram below shows what happens next. Your INavigateToItemProvider will get called with StartSearch(), and passed an INavigateToCallback. StartSearch() is an asynchronous request – you must return from this method as soon as possible, and conduct your search on a separate thread. For each match to the search term, instantiate a NavigateToItem object and send it to INavigateToCallback.AddItem(). But as the user types in the Search Terms field, NavigateTo will invoke your StartSearch() method repeatedly with the changing search term. When you receive the next StartSearch() message, you have to abandon your current search, and start a new one. You can't rely on receiving a StopSearch() message every time. Finally, when the Navigate To dialog box is closed by the user, you will get a Dispose() message – that's your cue to abandon any uncompleted searches, and dispose any resources you might be using as part of your search. While you conduct your search invoke INavigateToCallback.ReportProgress() occasionally to provide feedback about how close you are to completing the search. There does not appear to be any particular requirement to how often you invoke ReportProgress(), and you report your progress as the ratio of two integers. In my implementation I report progress in terms of the number of symbols I've searched over the total number of symbols in my dictionary, and send a progress report every 16 symbols. Displaying the Results The Navigate to framework invokes INavigateToItemDisplayProvider.CreateItemDisplay() once for each result you passed to the INavigateToCallback. CreateItemDisplay() is passed the NavigateToItem you handed to the callback, and must return an INavigateToItemDisplay object. NavigateToItem is a sealed class which has a few properties, including the name of the symbol. It also has a Tag property, of type object. This enables you to stash away all the information you will need to create your INavigateToItemDisplay, which must implement an INavigateTo() method to display a symbol in an editor IDE when the user double-clicks an entry in the Navigate To dialog box. Since the tag is of type object, it is up to you, the implementor, to decide what kind of object you store in here, and how it enables the retrieval of other information which is not included in the NavigateToItem properties. Some of the INavigateToItemDisplay properties are self-explanatory, but a couple of them are less obvious: Additional informationThe string you return here is displayed inside brackets on the same line as the Name property. In English locales, Visual Studio includes the preposition "of". If you look at the first line in the Navigate To screenshot at the top of this article, Book_WebRole.Default is the additional information for textBookAuthor, and is the namespace qualified type name the symbol appears in. For procedural COBOL code we display the Program Id as the additional information DescriptionItemsYou can use this property to return any textual description you want about the item currently selected. You return a collection of DescriptionItem objects, each of which has a category and description collection of DescriptionRun objects. A DescriptionRun enables you to specify some text, and optional formatting, so you have some control over the appearance of the displayed text. The DescriptionItems property is displayed at the bottom of the Navigate To dialog box, with the Categories on the left and the Descriptions on the right. The Visual COBOL implementation uses it to display more information about the location of an item, making it easier for the user to know disambiguate duplicate names (something there can be a lot of in large COBOL applications). Summary I hope this article is useful for anyone implementing Navigate To. It is a fantastic navigation feature that Microsoft have added to Visual Studio, but at the moment there still don't seem to be any examples on how to implement it, and the reference information on MSDN is a little brief for anyone attempting an implementation.

• Are you reporting Visual Studio 2012 issues to Microsoft correctly?

  - by Tarun Arora

  Issues you may run into while using Visual Studio need to be reported to the Microsoft Product Team via the Microsoft connect site. The Microsoft team then tries to reproduce the issue using the details provided by you. If the information you provide isn’t sufficient to reproduce the issue the team tries to contact you for specifics, this not only increases the cycle time to resolution but the lack of communication also results in issues not being resolved. So, when I report an issue one part of me tells me to include as much detail about the issue as I can clubbing screen shots, repo steps, system information, visual studio version information,… the other half tells me this is so time consuming, leave it for now and come back to fill all these details later. Reporting a bug but not including the supporting information is an invitation to excuses like …     Microsoft has absolutely changed this experience for VS 2012. The Microsoft Visual Studio Feedback tool is designed to simplify the process of providing feedback and reporting issues to Microsoft that you may encounter while using Microsoft Visual Studio 2012. Note – The Microsoft Visual Studio 2012 Feedback client currently only works for VS 2012 and not any other versions of Visual Studio. Setting up the Microsoft Visual Studio 2012 Feedback client Open Visual Studio, from the Tools menu select Extension and Updates. In the Extension and Updates window, click Online from the left pane and search using the text ‘feedback’, download and Install Microsoft Visual Studio 2012 Feedback Tool by following the instructions from the wizard. Note - Restarting Visual Studio after the install is a must! How to report a bug for Visual Studio 2012? Click on the Help menu and choose Report a Bug You should see an icon Microsoft Visual Studio 2012 Feedback Tool come up in the system tray icon area You’ll need to accept the Privacy statement. You have the option of reporting the feedback as private or public. Microsoft works with several Partners, MVP’s and Vendors who get access to early bits of Microsoft products for valuation. This is where it becomes essential to report the feedback privately. I would choose the Public option otherwise. After all if it’s out there in the public, others can discover and add to it easily. You now have the option to report a new issue or add to an existing issue. Should you choose to add to an existing issue you should have the feedback ID of the issue available. This can be obtained from the Microsoft Connect site. For now I am going to focus on reporting a new feedback privately. Filling out the feedback details You will notice that VsInfo.xml and DxDiagOutput.txt are automatically attached as you enter this screen (more on that later).  Feedback Type Choose the feedback type from (Performance, Hang, Crash, Other) Note – The record button will only be enabled once you have enabled once you have chosen the feedback type, Bug-repro recording is not available for Windows Server 2008.     Effective Title and Description Enter a title that helps us differentiate the bug when it appears in a list, so that we can group it with any related bugs, assign it to a developer more effectively, and resolve it more quickly. Example: Imagine that you are submitting a bug because you tried to install Service Pack 1 and got a message that Visual Studio is not installed even though it is. Helpful:  Installed Visual Studio version not detected during Service Pack 1 setup. Not helpful:  Service Pack 1 problem. Tip: Write the problem description first, and then distil it to create a title. Example Description: Helpful: When I run Service Pack 1 Setup, I get the message "No Visual Studio version is detected" even though I have Visual Studio 2010 Ultimate and Visual C++ 2010 Express installed on my machine. Even though I uninstalled both editions, and then first reinstalled Ultimate and then Express, I still get the message. Record: Becoming a first class citizen Often a repro report is invaluable to describe and decipher the issue. Please use this feature to send actionable feedback. The record repro feature works differently depending on the feedback type you selected. Please find below details for each recording option. You can start recording simply by selecting a feedback type, and clicking on the “Record” button. When "Performance" is the bug type: When the Microsoft Visual Studio trace recorder starts, perform the actions that show the performance problem you want to report and then click on the "Stop Recording" button as soon as you experience the performance problem. Because the tool optimizes trace collection, you can run it for as long as it takes to show the problem, up to two hours. Note that, you need to stop recording as soon as the performance issue occurs, because the tool captures only the last couple minutes of your actions to optimize the trace collection. After you stop the recording, the tool takes up to two minutes to assemble the data and attach an ETLTrace.zip file to your bug report. The data includes information about Windows events and the Visual Studio code path. Note that, running the Microsoft Visual Studio trace recorder requires elevated user privilege. When "Crash" is the bug type: When the dialog box appears, select the running Visual Studio instance for which you want to show the steps that cause a crash. When the crash occurs, click on the "Stop Record" button. After you do this, two files are attached to your bug report - an AutomaticCrashDump.zip file that contains information about the crash and a ReproSteps.zip file that shows the repro steps. Repro steps are captured by Windows Problem Steps Recorder. Note that, you can pause the recording, and resume later, or for a specific step, you can add additional comments. When "Hang" is the bug type: The process for recording the steps that cause a hang resembles the one for crashes. The difference is, you can even collect a dump file after the VS hangs; start the VSFT either from the system tray or by starting a new instance of VS, select "Hang" as feedback type and click on the "Record" button. You will be prompted which VS to collect dump about, select the VS instance that hanged. VSFT collects a dump file regarding the hang, called MiniDump.zip, and attaches to your bug report. When "Other" is the bug type: When the problem step recorder starts, perform the actions that show the issue you want to report and then choose the "Stop” button. You can pause the recording, and resume later, or for a specific step, you can add additional comments. Once you’re done, ReproSteps.zip is added to your bug report. Pre-attached files It is essential for Microsoft to know what version of the the product are you currently using and what is the current configuration of your system. Note – The total size of all attachments in a bug report cannot exceed 2 GB, and every uncompressed attachment must be smaller than 512 MB. We recommend that you assemble all of your attachments, compress them together into a .zip file, and then attach the .zip file. Taking a screenshot Associate a screen shot by clicking the Take screenshot button, choose either the entire desktop, the specific monitor (useful if you are working in a multi monitor configuration) or the specific window in question. And finally … click Submit If you need further help, more details can be found here.

• Solution: Testing Web Services with MSTest on Team Build

  - by Martin Hinshelwood

  Guess what. About 20 minutes after I fixed the build, Allan broke it again! Update: 4th March 2010 – After having huge problems getting this working I read Billy Wang’s post which showed me the light. The problem here is that even though the test passes locally it will not during an Automated Build. When you send your tests to the build server it does not understand that you want to spin up the web site and run tests against that! When you run the test in Visual Studio it spins up the web site anyway, but would you expect your test to pass if you told the website not to spin up? Of course not. So, when you send the code to the build server you need to tell it what to spin up. First, the best way to get the parameters you need is to right click on the method you want to test and select “Create Unit Test”. This will detect wither you are running in IIS or ASP.NET Development Server or None, and create the relevant tags. Figure: Right clicking on “SaveDefaultProjectFile” will produce a context menu with “Create Unit tests…” on it. If you use this option it will AutoDetect most of the Attributes that are required. /// <summary> ///A test for SSW.SQLDeploy.SilverlightUI.Web.Services.IProfileService.SaveDefaultProjectFile ///</summary> // TODO: Ensure that the UrlToTest attribute specifies a URL to an ASP.NET page (for example, // http://.../Default.aspx). This is necessary for the unit test to be executed on the web server, // whether you are testing a page, web service, or a WCF service. [TestMethod()] [HostType("ASP.NET")] [AspNetDevelopmentServerHost("D:\\Workspaces\\SSW\\SSW\\SqlDeploy\\DEV\\Main\\SSW.SQLDeploy.SilverlightUI.Web", "/")] [UrlToTest("http://localhost:3100/")] [DeploymentItem("SSW.SQLDeploy.SilverlightUI.Web.dll")] public void SaveDefaultProjectFileTest() { IProfileService target = new ProfileService(); // TODO: Initialize to an appropriate value string strComputerName = string.Empty; // TODO: Initialize to an appropriate value bool expected = false; // TODO: Initialize to an appropriate value bool actual; actual = target.SaveDefaultProjectFile(strComputerName); Assert.AreEqual(expected, actual); Assert.Inconclusive("Verify the correctness of this test method."); } Figure: Auto created code that shows the attributes required to run correctly in IIS or in this case ASP.NET Development Server If you are a purist and don’t like creating unit tests like this then you just need to add the three attributes manually. HostType – This attribute specified what host to use. Its an extensibility point, so you could write your own. Or you could just use “ASP.NET”. UrlToTest – This specifies the start URL. For most tests it does not matter which page you call, as long as it is a valid page otherwise your test may not run on the server, but may pass anyway. AspNetDevelopmentServerHost – This is a nasty one, it is only used if you are using ASP.NET Development Host and is unnecessary if you are using IIS. This sets the host settings and the first value MUST be the physical path to the root of your web application. OK, so all that was rubbish and I could not get anything working using the MSDN documentation. Google provided very little help until I ran into Billy Wang’s post  and I heard that heavenly music that all developers hear when understanding dawns that what they have been doing up until now is just plain stupid. I am sure that the above will work when I am doing Web Unit Tests, but there is a much easier way when doing web services. You need to add the AspNetDevelopmentServer attribute to your code. This will tell MSTest to spin up an ASP.NET Development server to host the service. Specify the path to the web application you want to use. [AspNetDevelopmentServer("WebApp1", "D:\\Workspaces\\SSW\\SSW\\SqlDeploy\\DEV\\Main\\SSW.SQLDeploy.SilverlightUI.Web")] [DeploymentItem("SSW.SQLDeploy.SilverlightUI.Web.dll")] [TestMethod] public void ProfileService_Integration_SaveDefaultProjectFile_Returns_True() { ProfileServiceClient target = new ProfileServiceClient(); bool isTrue = target.SaveDefaultProjectFile("Mav"); Assert.AreEqual(true, isTrue); } Figure: This AspNetDevelopmentServer will make sure that the specified web application is launched. Now we can run the test and have it pass, but if the dynamically assigned ASP.NET Development server port changes what happens to the details in your app.config that was generated when creating a reference to the web service? Well, it would be wrong and the test would fail. This is where Billy’s helper method comes in. Once you have created an instance of your service call, and it has loaded the config, but before you make any calls to it you need to go in and dynamically set the Endpoint address to the same address as your dynamically hosted Web Application. using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.VisualStudio.TestTools.UnitTesting; using System.Reflection; using System.ServiceModel.Description; using System.ServiceModel; namespace SSW.SQLDeploy.Test { class WcfWebServiceHelper { public static bool TryUrlRedirection(object client, TestContext context, string identifier) { bool result = true; try { PropertyInfo property = client.GetType().GetProperty("Endpoint"); string webServer = context.Properties[string.Format("AspNetDevelopmentServer.{0}", identifier)].ToString(); Uri webServerUri = new Uri(webServer); ServiceEndpoint endpoint = (ServiceEndpoint)property.GetValue(client, null); EndpointAddressBuilder builder = new EndpointAddressBuilder(endpoint.Address); builder.Uri = new Uri(endpoint.Address.Uri.OriginalString.Replace(endpoint.Address.Uri.Authority, webServerUri.Authority)); endpoint.Address = builder.ToEndpointAddress(); } catch (Exception e) { context.WriteLine(e.Message); result = false; } return result; } } } Figure: This fixes a problem with the URL in your web.config not being the same as the dynamically hosted ASP.NET Development server port. We can now add a call to this method after we created the Proxy object and change the Endpoint for the Service to the correct one. This process is wrapped in an assert as if it fails there is no point in continuing. [AspNetDevelopmentServer("WebApp1", D:\\Workspaces\\SSW\\SSW\\SqlDeploy\\DEV\\Main\\SSW.SQLDeploy.SilverlightUI.Web")] [DeploymentItem("SSW.SQLDeploy.SilverlightUI.Web.dll")] [TestMethod] public void ProfileService_Integration_SaveDefaultProjectFile_Returns_True() { ProfileServiceClient target = new ProfileServiceClient(); Assert.IsTrue(WcfWebServiceHelper.TryUrlRedirection(target, TestContext, "WebApp1")); bool isTrue = target.SaveDefaultProjectFile("Mav"); Assert.AreEqual(true, isTrue); } Figure: Editing the Endpoint from the app.config on the fly to match the dynamically hosted ASP.NET Development Server URL and port is now easy. As you can imagine AspNetDevelopmentServer poses some problems of you have multiple developers. What are the chances of everyone using the same location to store the source? What about if you are using a build server, how do you tell MSTest where to look for the files? To the rescue is a property called" “%PathToWebRoot%” which is always right on the build server. It will always point to your build drop folder for your solutions web sites. Which will be “\\tfs.ssw.com.au\BuildDrop\[BuildName]\Debug\_PrecompiledWeb\” or whatever your build drop location is. So lets change the code above to add this. [AspNetDevelopmentServer("WebApp1", "%PathToWebRoot%\\SSW.SQLDeploy.SilverlightUI.Web")] [DeploymentItem("SSW.SQLDeploy.SilverlightUI.Web.dll")] [TestMethod] public void ProfileService_Integration_SaveDefaultProjectFile_Returns_True() { ProfileServiceClient target = new ProfileServiceClient(); Assert.IsTrue(WcfWebServiceHelper.TryUrlRedirection(target, TestContext, "WebApp1")); bool isTrue = target.SaveDefaultProjectFile("Mav"); Assert.AreEqual(true, isTrue); } Figure: Adding %PathToWebRoot% to the AspNetDevelopmentServer path makes it work everywhere. Now we have another problem… this will ONLY run on the build server and will fail locally as %PathToWebRoot%’s default value is “C:\Users\[profile]\Documents\Visual Studio 2010\Projects”. Well this sucks… How do we get the test to run on any build server and any developer laptop. Open “Tools | Options | Test Tools | Test Execution” in Visual Studio and you will see a field called “Web application root directory”. This is where you override that default above. Figure: You can override the default website location for tests. In my case I would put in “D:\Workspaces\SSW\SSW\SqlDeploy\DEV\Main” and all the developers working with this branch would put in the folder that they have mapped. Can you see a problem? What is I create a “$/SSW/SqlDeploy/DEV/34567” branch from Main and I want to run tests in there. Well… I would have to change the value above. This is not ideal, but as you can put your projects anywhere on a computer, it has to be done. Conclusion Although this looks convoluted and complicated there are real problems being solved here that mean that you have a test ANYWHERE solution. Any build server, any Developer workstation.
