• TechEd 2012: MVVM In XAML

  - by Tim Murphy

  Paul Sheriff was a real character at the start of his MVVM in XAML session.  There was a lot of sarcasm and self deprecation going on prior to the .  That is never a bad way to get things rolling right after lunch.  Then things got semi-serious. The presentation itself had a number of surprises, but not all of them had to do with XAML.  When he flipped over his company’s code generation tool it took me off guard.  I am used to generator that create code for a whole project, but his tools were able to create different types of constructs on demand.  It also made it easier to follow what he was doing than some of the other demos I have seen this week where people were using code snippets. Getting to the heart of the topic I found myself thinking that I may have found my utopia for application development in MVVM.  Yes, I know there is no such thing, but this comes closer than any other pattern I have learned about.  This pattern allows the application to have better separation of concerns than I have seen before.  This is especially true since you can leverage data binding.  I’m not sure why it has taken me so long to find time for this subject. As Paul demonstrated using this pattern with XAML gives you multi-platform reusable code when you leverage common utility classes and ModelView classes.  The one drawback I see is that you have to go to the lowest common denominator between the platforms you want to support, but you always have to weigh the trade offs. And finally, the Visual Studio nuggets just keep coming.  Even though it has been available for several generations of Visual Studio I have never seen someone use linked files within a solution.  It just goes to show that I should spend more time exploring the deeper features of each dialog. del.icio.us Tags: TechEd,TechEd 2012,MVVM,Paul Sheriff,Patterns,Visual Studio 2012

• Resource Acquisition is Initialization in C#

  - by codeWithoutFear

  Resource Acquisition Is Initialization (RAII) is a pattern I grew to love when working in C++.  It is perfectly suited for resource management such as matching all those pesky new's and delete's.  One of my goals was to limit the explicit deallocation statements I had to write.  Often these statements became victims of run-time control flow changes (i.e. exceptions, unhappy path) or development-time code refactoring. The beauty of RAII is realized by tying your resource creation (acquisition) to the construction (initialization) of a class instance.  Then bind the resource deallocation to the destruction of that instance.  That is well and good in a language with strong destructor semantics like C++, but languages like C# that run on garbage-collecting runtimes don't provide the same instance lifetime guarantees. Here is a class and sample that combines a few features of C# to provide an RAII-like solution: using System; namespace RAII { public class DisposableDelegate : IDisposable { private Action dispose; public DisposableDelegate(Action dispose) { if (dispose == null) { throw new ArgumentNullException("dispose"); } this.dispose = dispose; } public void Dispose() { if (this.dispose != null) { Action d = this.dispose; this.dispose = null; d(); } } } class Program { static void Main(string[] args) { Console.Out.WriteLine("Some resource allocated here."); using (new DisposableDelegate(() => Console.Out.WriteLine("Resource deallocated here."))) { Console.Out.WriteLine("Resource used here."); throw new InvalidOperationException("Test for resource leaks."); } } } } The output of this program is: Some resource allocated here. Resource used here. Unhandled Exception: System.InvalidOperationException: Test for resource leaks. at RAII.Program.Main(String[] args) in c:\Dev\RAII\RAII\Program.cs:line 40 Resource deallocated here. Code without fear! --Don

• One Week on New Servers and Everything is Great

  - by Jeff Julian

  It has been a week since we moved our Geekswithblogs.net System to a new set of load balanced servers and everything has been going great.  I am so amazed at the performance of the new hardware.  On average, we only use less than 5% of the CPU at any given moments or the database and web servers.  I have seen a performance boost in page load as well, but I will have to confirm that with the statistics as they roll in.  This is all in preparation for a new community we are launching with some friends that we will be announcing shortly.  We will be launching a nice little contest for our bloggers as well.

• Obfuscation is not a panacea

  - by simonc

  So, you want to obfuscate your .NET application. My question to you is: Why? What are your aims when your obfuscate your application? To protect your IP & algorithms? Prevent crackers from breaking your licensing? Your boss says you need to? To give you a warm fuzzy feeling inside? Obfuscating code correctly can be tricky, it can break your app if applied incorrectly, it can cause problems down the line. Let me be clear - there are some very good reasons why you would want to obfuscate your .NET application. However, you shouldn't be obfuscating for the sake of obfuscating. Security through Obfuscation? Once your application has been installed on a user’s computer, you no longer control it. If they do not want to pay for your application, then nothing can stop them from cracking it, even if the time cost to them is much greater than the cost of actually paying for it. Some people will not pay for software, even if it takes them a month to crack a $30 app. And once it is cracked, there is nothing stopping them from putting the result up on the internet. There should be nothing suprising about this; there is no software protection available for general-purpose computers that cannot be cracked by a sufficiently determined attacker. Only by completely controlling the entire stack – software, hardware, and the internet connection, can you have even a chance to be uncrackable. And even then, someone somewhere will still have a go, and probably succeed. Even high-end cryptoprocessors have known vulnerabilities that can be exploited by someone with a scanning electron microscope and lots of free time. So, then, why use obfuscation? Well, the primary reason is to protect your IP. What obfuscation is very good at is hiding the overall structure of your program, so that it’s very hard to figure out what exactly the code is doing at any one time, what context it is running in, and how it fits in with the rest of the application; all of which you need to do to understand how the application operates. This is completely different to cracking an application, where you simply have to find a single toggle that determines whether the application is licensed or not, and flip it without the rest of the application noticing. However, again, there are limitations. An obfuscated application still has to run in the same way, and do the same thing, as the original unobfuscated application. This means that some of the protections applied to the obfuscated assembly have to be undone at runtime, else it would not run on the CLR and do the same thing. And, again, since we don’t control the environment the application is run on, there is nothing stopping a user from undoing those protections manually, and reversing some of the obfuscation. It’s a perpetual arms race, and it always will be. We have plenty of ideas lined about new protections, and the new protections added in SA 6.6 (method parent obfuscation and a new control flow obfuscation level) are specifically designed to be harder to reverse and reconstruct the original structure. So then, by all means, obfuscate your application if you want to protect the algorithms and what the application does. That’s what SmartAssembly is designed to do. But make sure you are clear what a .NET obfuscator can and cannot protect you against, and don’t expect your obfuscated application to be uncrackable. Someone, somewhere, will crack your application if they want to and they don’t have anything better to do with their time. The best we can do is dissuade the casual crackers and make it much more difficult for the serious ones. Cross posted from Simple Talk.

• A .NET Developers day with the iPad.

  - by mbcrump

  The Apple iPad is currently getting a lot of buzz because of the app store, the book store and of course iTunes. I had the chance to play with one and this is what I have learned about the device. Let’s get this out of the way first, the iPad is awesome. It is the device for media consumption and casual web browsing. But how does it measure up to those of us with .NET on our brains all days. Let’s find out… Main Screen – you can customize everything on this page. I guess I should replace that image with a C# or VS logo. Its pretty standard stuff if you have an iPhone.   Programming Books If you have a subscription to Safari Books Online, then you are in luck, its very easy to read the books on the iPad. Just fire up Safari web browser and goto the Safari Books Online. The biggest benefit that I can see with the iPad is the ability to read books wherever and not have to worry about purchasing books that I already have the .PDF for. Below is a sample from Code Complete 2nd Edition. Below is a PDF of the ECMA-334 C# Language Specification. As you can see its very readable and you should have no problem reading actual code.   Example of Code shown below: It is however easier to read the PDF and store them with a 3rd party PDF reader. I have seen several for .99 cents or less. You can however switch the screen to vertical to get more viewing space as shown below: I was disappointed with the iBooks application. I could not find a single .NET programming book anywhere. I was able to download the excellent sci-fi book “A memory of Wind” for free though. If I just overlooked them, then please email me with the names and titles. I couldn’t even find a technology category in the categories list. Web Surfing – Technical Sites Below is an example of my site in Safari. The code is very readable and the experience was identical to viewing it in Firefox. I tried multiple programming site and the pages looked great except those that used flash and of course it did not display on those pages.   News Apps - Technical Content The standard NY Times and USA Today looked great, but the Technical Content was lacking. It would probably be better to use Google Reader for online technical news.     YouTube Videos – Technical Content  Since its YouTube, we already know that a lot of technical content exist and it plays great on the iPad. I watched several programming videos and could clearly see the code being written. Taking Technical Notes The iPad comes with a great notepad for taking notes. I found that it was easy to take notes regarding projects that I am currently working on.   Calendar The calendar that ships with the iPad is great for organizing. You can setup exchange server or manually enter the information. Pretty standard stuff.    Random Applications that I like: TweetDeck.   and Adobe Ideas. Adobe Ideas is kinda like SketchFlow except you use your finger to mock up the sketches.  Don’t forget that the iPad is great for any type of podcasting. That pretty much sums it up, I would definitely recommend this device as it will only get better. I believe the iOS4 comes out on the 24th and the iPad will only get more and more apps. You could save a few bucks by waiting for the 2nd generation, but that’s a call that only you can make.

• Formatting made easy - Silverlight 4

  - by PeterTweed

  One of the simplest tasks in business apps is displaying different types of data to be read in the format that the user expects them.  In Silverlight versions until Silverlight 4 this has meant using a Converter to format data during binding.  This involves writing code for the formatting of the data to bind, instead of simply defining the formatting to use for the data in question where you bind the data to the control.   In Silverlight 4 we find the addition of the StringFormat markup extension that allows us to do exactly this.  Of course the nice thing is the ability to use the common formatting conventions available in C# through the String.Format function.   This post will show you how to use three of the common formatting conventions - currency, a defined number of decimal places for a number and a date format.   Steps:   1. Create a new Silverlight 4 application   2. In the body of the MainPage.xaml.cs file replace the MainPage class with the following code:       public partial class MainPage : UserControl     {         public MainPage()         {             InitializeComponent();             this.Loaded += new RoutedEventHandler(MainPage_Loaded);         }           void MainPage_Loaded(object sender, RoutedEventArgs e)         {             info i = new info() { PriceValue = new Decimal(9.2567), DoubleValue = 1.2345678, DateValue = DateTime.Now };             this.DataContext = i;         }     }         public class info     {         public decimal PriceValue { get; set; }         public double DoubleValue { get; set; }         public DateTime DateValue { get; set; }     }   This code defines a class called info with different data types for the three properties.  A new instance of the class is created and bound to the DataContext of the page.   3.  In the MainPage.xaml file copy the following XAML into the LayoutRoot grid:           <Grid.RowDefinitions>             <RowDefinition Height="60*" />             <RowDefinition Height="28*" />             <RowDefinition Height="28*" />             <RowDefinition Height="30*" />             <RowDefinition Height="154*" />         </Grid.RowDefinitions>         <Grid.ColumnDefinitions>             <ColumnDefinition Width="86*" />             <ColumnDefinition Width="314*" />         </Grid.ColumnDefinitions>         <TextBlock Grid.Row="1" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock1" Text="Price Value:" VerticalAlignment="Top" />         <TextBlock Grid.Row="2" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock2" Text="Decimal Value:" VerticalAlignment="Top" />         <TextBlock Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock3" Text="Date Value:" VerticalAlignment="Top" />         <TextBlock Grid.Column="1" Grid.Row="1" Height="23" HorizontalAlignment="Left" Name="textBlock4" Text="{Binding PriceValue, StringFormat='C'}" VerticalAlignment="Top" Margin="6,0,0,0" />         <TextBlock Grid.Column="1" Grid.Row="2" Height="23" HorizontalAlignment="Left" Margin="6,0,0,0" Name="textBlock5" Text="{Binding DoubleValue, StringFormat='N3'}" VerticalAlignment="Top" />         <TextBlock Grid.Column="1" Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="6,0,0,0" Name="textBlock6" Text="{Binding DateValue, StringFormat='yyyy MMM dd'}" VerticalAlignment="Top" />   This XAML defines three textblocks that use the StringFormat markup extension.  The three examples use the C for currency, N3 for a number with 3 decimal places and yyy MM dd for a date that displays year 3 letter month and 2 number date.   4. Run the application and see the data displayed with the correct formatting. It's that easy!

• Visual Studio 2010 - Faster Startup with /nosplash

  - by MikeParks

  I read a blog the other day about the /nosplash switch in Visual Studio. Apparently, it's been around a while and I'm a little late on finding out about it. I figured I'd share it for those of you that come across this and didn't know about it as well. Basically all it does is turn off the Visual Studio splash screen which speeds up initial startup time. It's not a big difference but every little bit helps. I choose speed over looks. You can set the switch by right clicking on Visual Studio, selecting Properties, and adding "/nosplash" on the target Property, so it will look like this: "C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /nosplash. Feel free to try it out and see if you like it. You can always change it back by just removing the /nosplash switch when you're done testing. There are plenty more Visual Studio switches out there but this is the main one that came in handy for me.   - Mike

• Life Is Full Of Changes (Part 1)

  - by Brian Jackett

  Today will be my last day with Sogeti.  I’ve been with Sogeti USA for just over 4 years.  In that time I’ve gotten to work on some great projects, develop relationships with some brilliant and passionate people, participate in the .Net developer and SharePoint communities, and grow my skills in a number of areas I’m passionate about.     As with all good things they must come to an end though.  I’ve accepted a position with another company and will provide more details once the transition has completed.  This decision was a difficult one to make but it provides a great career opportunity on many levels.  As much as my new schedule allows I plan to continue participating in local user groups, speaking at conferences, and blogging.     Speaking of which, you may have noticed my reduced blogging activity in the past few months.  In addition to a career change I’m also in the process of moving to a new residence (only a few miles from my current residence, so I’ll still be in Columbus.)  Searching for a new place, filling out paperwork, and all of the other work associated with this move has taken away a good chunk of the time I used to devote to blogging.  Once everything gets settled out with the move and job change I’ll re-evaluate how much time I can devote to blogging.     A big thanks to Sogeti and everyone who has been so supportive over my time with them.  It’s hard to move on, but I am excited for the prospects that the future will bring.         -Frog Out

• No More NCrunch For Me

  - by Steve Wilkes

  When I opened up Visual Studio this morning, I was greeted with this little popup: NCrunch is a Visual Studio add-in which runs your tests while you work so you know if and when you've broken anything, as well as providing coverage indicators in the IDE and coverage metrics on demand. It recently went commercial (which I thought was fair enough), and time is running out for the free version I've been using for the last couple of months. From my experiences using NCrunch I'm going to let it expire, and go about my business without it. Here's why. Before I start, let me say that I think NCrunch is a good product, which is to say it's had a positive impact on my programming. I've used it to help test-drive a library I'm making right from the start of the project, and especially at the beginning it was very useful to have it run all my tests whenever I made a change. The first problem is that while that was cool to start with, it’s recently become a bit of a chore. Problems Running Tests NCrunch has two 'engine modes' in which it can run tests for you - it can run all your tests when you make a change, or it can figure out which tests were impacted and only run those. Unfortunately, it became clear pretty early on that that second option (which is marked as 'experimental') wasn't really working for me, so I had to have it run everything. With a smallish number of tests and while I was adding new features that was great, but I've now got 445 tests (still not exactly loads) and am more in a 'clean and tidy' mode where I know that a change I'm making will probably only affect a particular subset of the tests. With that in mind it's a bit of a drag sitting there after I make a change and having to wait for NCrunch to run everything. I could disable it and manually run the tests I know are impacted, but then what's the point of having NCrunch? If the 'impacted only' engine mode worked well this problem would go away, but that's not what I found. Secondly, what's wrong with this picture? I've got 445 tests, and NCrunch has queued 455 tests to run. So it's queued duplicate tests - in this quickly-screenshotted case 10, but I've seen the total queue get up over 600. If I'm already itchy waiting for it to run all my tests against a change I know only affects a few, I'm even itchier waiting for it to run a lot of them twice. Problems With Code Coverage NCrunch marks each line of code with a dot to say if it's covered by tests - a black dot says the line isn't covered, a red dot says it's covered but at least one of the covering tests is failing, and a green dot means all the covering tests pass. It also calculates coverage statistics for you. Unfortunately, there's a couple of flaws in the coverage. Firstly, it doesn't support ExcludeFromCodeCoverage attributes. This feature has been requested and I expect will be included in a later release, but right now it doesn't. So this: ...is counted as a non-covered line, and drags your coverage statistics down. Hmph. As well as that, coverage of certain types of code is missed. This: ...is definitely covered. I am 100% absolutely certain it is, by several tests. NCrunch doesn't pick it up, down go my coverage statistics. I've had NCrunch find genuinely uncovered code which I've been able to remove, and that's great, but what's the coverage percentage on this project? Umm... I don't know. Conclusion None of these are major, tool-crippling problems, and I expect NCrunch to get much better in future releases. The current version has some great features, like this: ...that's a line of code with a failing test covering it, and NCrunch can run that failing test and take me to that line exquisitely easily. That's awesome! I'd happily pay for a tool that can do that. But here's the thing: NCrunch (currently) costs $159 (about £100) for a personal licence and $289 (about £180) for a commercial one. I'm not sure which one I'd need as my project is a personal one which I'm intending to open-source, but I'm a professional, self-employed developer, but in any case - that seems like a lot of money for an imperfect tool. If it did everything it's advertised to do more or less perfectly I'd consider it, but it doesn't. So no more NCrunch for me.

• String manipulation functions in SQL Server 2000 / 2005

  - by Vipin

  SQL Server provides a range of string manipulation functions. I was aware of most of those in back of the mind, but when I needed to use one, I had to dig it out either from SQL server help file or from google. So, I thought I will list some of the functions which performs some common operations in SQL server. Hope it will be helpful to you all. Len (' String_Expression' ) - returns the length of input String_Expression. Example - Select Len('Vipin') Output - 5 Left ( 'String_Expression', int_characters ) - returns int_characters characters from the left of the String_Expression.     Example - Select Left('Vipin',3), Right('Vipin',3) Output -  Vip,  Pin  LTrim ( 'String_Expression' ) - removes spaces from left of the input 'String_Expression'  RTrim ( 'String_Expression' ) - removes spaces from right of the input 'String_Expression' Note - To removes spaces from both ends of the string_expression use Ltrim and RTrim in conjunction Example - Select LTrim(' Vipin '), RTrim(' Vipin ') , LTrim ( RTrim(' Vipin ')) Output - 'Vipin ' , ' Vipin' , 'Vipin' (Single quote marks ' ' are not part of the SQL output, it's just been included to demonstrate the presence of space at the end of string.) Substring ( 'String_Expression' , int_start , int_length ) - this function returns the part of string_expression. Right ( 'String_Expression', int_characters ) - returns int_characters characters from the right of the String_Expression.

• Silverlight Binding with multiple collections

  - by George Evjen

  We're designing some sport specific applications. In one of our views we have a gridview that is bound to an observable collection of Teams. This is pretty straight forward in terms of getting Teams bound to the GridView. <telerik:RadGridView Grid.Row="0" Grid.Column="0" x:Name="UsersGrid" ItemsSource="{Binding TeamResults}" SelectedItem="{Binding SelectedTeam, Mode=TwoWay}"> <telerik:RadGridView.Columns> <telerik:GridViewDataColumn Header="Name/Group" DataMemberBinding="{Binding TeamName}" MinWidth="150"></telerik:GridViewDataColumn> </telerik:RadGridView.Columns> </telerik:RadGridView> We use the observable collection of teams as our items source and then bind the property of TeamName to the first column. You can set the binding to mode=TwoWay, we use a dialog where we edit the selected item, so our binding here is not set to two way. The issue comes when we want to bind to a property that has another collection in it. To continue on our code from above, we have an observable collection of teams, within that collection we have a collection of KeyPeople. We get this collection using RIA Serivces with the code below. return _TeamsRepository.All().Include("KeyPerson"); Here we are getting all the teams and also including the KeyPerson entity. So when we are done with our Load we will end up with an observable collection of Teams with a navigation property / entity of KeyPerson. Within this KeyPerson entity is a list of people associated with that particular team. We want to display the head coach from this list of KeyPersons. This list currently has a list of ten or more people that are bound to this team, but we just want to display the Head Coach in the column next to team name. The issue becomes how do we bind to this included entity? I have found about three different ways to solve this issue. The way that seemed to fit us best is to utilize the features within RIA Services. We can create client side properties that will do the work for us. We will create in the client side library a partial class of Team. We will end up in our library a file that is Team.shared.cs. The code below is what we will put into our partial team class. public KeyPerson Coach        {            get            {                if (this.KeyPerson != null && this.KeyPerson.Any())                { return this.KeyPerson.Where(x => x.RelationshipType == “HeadCoach”).FirstOrDefault(); }                 return null;            }        } We will return just the person that is the Head Coach and then be able to bind that and any other additional properties that we need. <telerik:GridViewDataColumn Header="Coach" DataMemberBinding="{Binding Coach.Name}" MinWidth="150"></telerik:GridViewDataColumn> There are other ways that we could have solved this issue but we felt that creating a partial class through RIA Services best suited our needs.

• Adventures in Lab Management Configuration: CMMI Edition Part 1 of 3

  - by Enrique Lima

  I remember at one point someone telling me how close Migrate was to Migraine. This was a process that included an environment from TFS 2008 to TFS 2010, needed to be migrated too as far as the process template goes.  Here we are talking about CMMI v4.2 to CMMI v5.0.  Now, the process to migrate the TFS Infrastructure is one thing, migrating the Process Template is a different deal, not hard … just involved. Followed a combination of steps that came from a blog post as the main guidance and then MSDN (as suggested on the guidance post) to complement some tasks and steps. Again, the focus I have here is CMMI. The high level steps taken to enable the TFS 2008 CMMI v4.2 migrated to TFS 2010 Process Template are: 1)  Backup the Collection, Configuration and Warehouse Databases. 2)  Downloaded the Process Template using Visual Studio 2010. 3) Exported, modified and imported Bug Type Definition 4) Exported, modified and imported Scenario or Requirement Type Definition. 5) Created and imported bug field mappings. Now, we can attempt to connect using Test Manager, and you should be able to get this going. After that was done, it was time to enroll VMs that already existed in the environment.  This was a bit more challenging, but in the end it was a matter of just analyzing the changes that had been made to had a temporary work around from the time we migrated to the time we converted the Work Items and such and added fields to enable communication between the project and the Test and Lab Manager component. There are 2 more parts to this post, the second will describe the detailed steps taken to complete the Process Template update and the third will talk about the gotchas and fixes for the Lab Management portion.

• Repeater vs. ListView

  - by MoezMousavi

  I do really hate repeater. I was more a GridView lover but after 3.5 be born, I prefer ListView.  The first problem with Repeater is paging. You will need to write code to handle paging. Second common problem is empty data template. Have a look at this:             if (rptMyRepeater.Items.Count < 1)             {                 if (e.Item.ItemType == ListItemType.Footer)                 {                     Label lblFooter = (Label)e.Item.FindControl("lblEmpty");                     lblFooter.Visible = true;                 }             }   I found the above code is usefull if you need to show something like "There is no record" is your data source has no records. Although the ListView has a template.   If you combine ListView with a DataPager, you will be in heaven as it is sorting the paging for you without writing code. (http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.datapager.aspx)     Note: You have got to bind ListView in PreRender, it doesn't work properly in PageLoad   More: http://www.4guysfromrolla.com/articles/061009-1.aspx

• From the Coal Face - StyleCop 4.4.0

  - by TATWORTH

  Style Cop 4.4.0 is now out. This is a free download from http://stylecop.codeplex.com/ (please note the new location). This version is for VS2010. If you are usign an older version of Visual Studio you be prepared to keep to an older release like 4.3.0. The more I use StyleCop the more I like it. Code that is style cop compliant is much easier to pick up. It helps if you have GhostDoc (free) and Resharper (from jetBrains.Com)

• Leadership Tip&ndash;Vent Up!

  - by D'Arcy Lussier

  Leadership is difficult, for many reasons. One of those reasons is that we not only need to keep ourselves motivated when difficult or challenging times come, but we also need to motivate our teams and keep them focussed on the tasks at hand regardless of the mortars being rained down around them. Inexperienced (and experienced) leaders can fall into the “me-too” mentality – that is, the leader sees themselves as part of the team member instead of the leader of the team. Once a leader changes the teams view that he/she is a peer and not the leader, dynamics can change on the team. One of the biggest dangers is that the leader starts sharing frustrations, fears, concerns, etc. with the team that they’re supposed to be leading on to victory. This can destroy a team’s morale and productivity. One simple thing you can do to counter this is remember this rule when it comes to venting: Vent Up! Don’t vent sideways or down, vent up. Vent to the people above you – they’re the ones that tend to have the power to actually change things anyway. You as a leader stay healthy by getting your frustrations and concerns off your chest, your team is still insulated from it, and your superiors are aware of issues that need to be addressed or can coach you through the obstacles.

• New Endpoint options that enable additional application patterns

  - by kaleidoscope

  The two communication-related capabilities:  a) inter-role communication and b) external endpoints on worker roles enable new application patterns in Windows Azure-hosted services. Inter-role Communication - A common application pattern enabled by this is client-server, where the server could be an application such as a database or a memory cache. External Endpoints on Worker Roles - A common application type enabled by this is a self-hosted Internet-exposed service, such as a custom application server.
