• Is committing/checking in code everyday a good practice?

  - by ArtB

  I've been reading Martin Fowler's note on Continuous Integration and he lists as a must "Everyone Commits To the Mainline Every Day". I do not like to commit code unless the section I'm working on is complete and that in practice I commit my code every three days: one day to investigate/reproduce the task and make some preliminary changes, a second day to complete the changes, and a third day to write the tests and clean it up^ for submission. I would not feel comfortable submitting the code sooner. Now, I pull changes from the repository and integrate them locally usually twice a day, but I do not commit that often unless I can carve out a smaller piece of work. Question: is committing everyday such a good practice that I should change my workflow to accomodate it, or it is not that advisable? Edit: I guess I should have clarified that I meant "commit" in the CVS meaning of it (aka "push") since that is likely what Fowler would have meant in 2006 when he wrote this. ^ The order is more arbitrary and depends on the task, my point was to illustrate the time span and activities, not the exact sequence.

• Strategy for hosting 700+ domains names, each with a static HTML site

  - by jonschlinkert

  I have a portfolio of more than 700 domain names, and ideally I'd like to put up a single-page HTML/CSS/JavaScript webpage for each domain. Is there a system/strategy/workflow that will allow me to: Automate the deployment of new websites, quickly and easily without having to manually initiate each new website in an admin panel. For instance, I've seen dropbox-based solutions that claim to make it simple to setup new websites on your dropbox account, but you still have to set each one up in an admin interface first. It would be so much easier to have a folder naming convention that allowed the user to easily clone/copy/duplicate sites inside their Dropbox App folder (https://www.dropbox.com/developers/blog/23) to create new ones. Sounds interesting, however... It's easy to manage CNAMEs on the registrar-side, but is there a way to quickly associate CNAMEs with new websites (on the hosting side), maybe using the method offered by gh-pages-style (https://help.github.com/articles/setting-up-a-custom-domain-with-pages)? With GitHub's gh-pages, all you have to do is drop a file called CNAME into your repo, with the domain name you want associated with the repo inside the file. gh-pages isn't a good solution for what I'm doing though unfortunately. I'm also a front-end developer, specializing in rapid web development and "front-end build systems", so I building and maintaining static assets for hundreds of sites is no problem. It's the hosting-side that I really struggle with. Any suggestions?

• Automatic syncing USB HD drive to local HD (different computers)

  - by luri

  I have a desktop PC at work, and a laptop at home.... or elsewhere. What I want to do is use a USB HD to store my documents (about 130 Gb, maybe more). That would serve as backup and also port my files to my laptop. I'd like any of both computers to automatically sync all files there with local copies, so that I can work at either of them and keep updated copies of everything in both (plus the USB drive, which would allow me to work in other computers, too, apart from being another backup). Dropbox ins't a solution for me, due to pricing and 100Gb limit. The workflow would be as follows, to clear things up: I work on PC1. Changes in files are automatically synced to USB whenever a file is modified. I go home and boot PC2. I plug the usb drive and local files are synced (if changed) with the most recent usb copies. While I work at PC2, again, changes in files spread to my USB drive. Whenever I go to PC1 again, I plug my usb and again everything synces. So the questions would be: a) Am I crazy? b) Can it be done? c) Will I have any file conflicts (provided I'm the only one that will modify the files)?

• Is a "model" branch a common practice?

  - by dukeofgaming

  I just thought it could be a good thing to have a dedicated version control branch for all database schema changes and I wanted to know if anyone else is doing the same and what have the results been. Say that you are working with: Schema model/documentation (some file where you model the database visually to generate the schema source, say MySQL Workbench, with a .mwb file, which is binary) Schema source (a .sql file) Schema-based code generation The normal way we were working was with feature branches, so we would do changes to the model files (the database specific ones), and then have to regenerate points 2 and 3, dealing with the possible conflicts (or even code rewriting). Now say that your workflow goes the same way as the previous item numbering. With a model branch you wouldn't have to reconcile the schema model with binaries in other feature branches, or have to regenerate schema source and regenerate code (which might have human code on top of it). It makes so much sense to me it feels weird not having seen this earlier as a common practice. Edit: I'm counting on branch merges to be the assertions for the model matching the code. I use a DVCS, so I don't fear long-lived branches or scary-looking merges. I'm also doing feature branching.

• Maintaining Two Separate Software Versions From the Same Codebase in Version Control

  - by Joseph

  Let's say that I am writing two different versions of the same software/program/app/script and storing them under version control. The first version is a free "Basic" version, while the second is a paid "Premium" version that takes the codebase of the free version and expands upon it with a few extra value-added features. Any new patches, fixes, or features need to find their way into both versions. I am currently considering using master and develop branches for the main codebase (free version) along side master-premium and develop-premium branches for the paid version. When a change is made to the free version and merged to the master branch (after thorough testing on develop of course), it gets copied over to the develop-premium branch via the cherry-pick command for more testing and then merged into master-premium. Is this the best workflow to handle this situation? Are there any potential problems, caveats, or pitfalls to be aware of? Is there a better branching strategy than what I have already come up with? Your feedback is highly appreciated! P.S. This is for a PHP script stored in Git, but the answers should apply to any language or VCS.

• Functions that only call other functions. Is this a good practice?

  - by Eric C.

  I'm currently working on a set of reports that have many different sections (all requiring different formatting), and I'm trying to figure out the best way to structure my code. Similar reports we've done in the past end up having very large (200+ line) functions that do all of the data manipulation and formatting for the report, such that the workflow looks something like this: DataTable reportTable = new DataTable(); void RunReport() { reportTable = DataClass.getReportData(); largeReportProcessingFunction(); outputReportToUser(); } I would like to be able to break these large functions up into smaller chunks, but I'm afraid that I'll just end up having dozens of non-reusable functions, and a similar "do everything here" function whose only job is to call all these smaller functions, like so: void largeReportProcessingFunction() { processSection1HeaderData(); calculateSection1HeaderAverages(); formatSection1HeaderDisplay(); processSection1SummaryTableData(); calculateSection1SummaryTableTotalRow(); formatSection1SummaryTableDisplay(); processSection1FooterData(); getSection1FooterSummaryTotals(); formatSection1FooterDisplay(); processSection2HeaderData(); calculateSection1HeaderAverages(); formatSection1HeaderDisplay(); calculateSection1HeaderAverages(); ... } Or, if we go one step further: void largeReportProcessingFunction() { callAllSection1Functions(); callAllSection2Functions(); callAllSection3Functions(); ... } Is this really a better solution? From an organizational point of view I suppose it is (i.e. everything is much more organized than it might otherwise be), but as far as code readability I'm not sure (potentially large chains of functions that only call other functions). Thoughts?

• What does SVN do better than git?

  - by doug

  No question that the majority of debates over programmer tools distill to either personal choice (by the user) or design emphasis, i.e., optimizing design according to particular uses cases (by the tool builder). Text Editors are probably the most prominent example--a coder who works on a Windows at work and codes in Haskell on the Mac at home, values cross-platform and compiler integration and so chooses Emacs over Textmate, etc. It's less common that a newly introduced technology is genuinely, demonstrably superior to the extant options. I wonder if this is in fact the case with version-control systems, in particular, centralized VCS (CVS, SVN) versus distributed VCS (git, hg)? I used SVN for about five years, and SVN is currently used where I work. A little less than three years ago, I switched to git (and gitHub) for all of my personal projects. I can think of a number of advantages of git over subversion (and which for the most part abstract to advantages of distributed over centralized VCS), but I cannot think of one contra example--some task (that's relevant and arises in a programmers usual workflow) that subversion does better than git. The only conclusion I have drawn from this is that I don't have any data--not that git is better, etc. My guess is that such counter-examples exist, hence this question.

• How do functional languages handle a mocking situation when using Interface based design?

  - by Programmin Tool

  Typically in C# I use dependency injection to help with mocking; public void UserService { public UserService(IUserQuery userQuery, IUserCommunicator userCommunicator, IUserValidator userValidator) { UserQuery = userQuery; UserValidator = userValidator; UserCommunicator = userCommunicator; } ... public UserResponseModel UpdateAUserName(int userId, string userName) { var result = UserValidator.ValidateUserName(userName) if(result.Success) { var user = UserQuery.GetUserById(userId); if(user == null) { throw new ArgumentException(); user.UserName = userName; UserCommunicator.UpdateUser(user); } } ... } ... } public class WhenGettingAUser { public void AndTheUserDoesNotExistThrowAnException() { var userQuery = Substitute.For<IUserQuery>(); userQuery.GetUserById(Arg.Any<int>).Returns(null); var userService = new UserService(userQuery); AssertionExtensions.ShouldThrow<ArgumentException>(() => userService.GetUserById(-121)); } } Now in something like F#: if I don't go down the hybrid path, how would I test workflow situations like above that normally would touch the persistence layer without using Interfaces/Mocks? I realize that every step above would be tested on its own and would be kept as atomic as possible. Problem is that at some point they all have to be called in line, and I'll want to make sure everything is called correctly.

• Packing up files on my machine, sending it to a server, and unpacking it

  - by MxyL

  I am implementing a feature in my application that sends all files in a specified folder to a server. I have the basic FTP transaction set up using Apache Commons FTPClient: it sets up a connection and transfers a file from one place to another. So I can simply loop over the directory and use this connection to transfer all the files. However, this could be better. Rather than transferring each file one by one, it makes more sense to pack it up in a compressed archive and then send the whole file at once. Saves time and bandwidth, since these are just text files so they compress nicely. So I would like to add automatic archive packing and unpacking. This is the workflow I have planned out, using zip compression: Zip all files in the folder Send the file over Unzip the files at its destination 1 and 2 are easy since the files are on the local machine, but I'm not sure how to accomplish the last step, when the files are now on a remote server. What are my options? I have control over what I can put and run on the server. Perhaps it is not necessary to do the packing/unpacking myself?

• Advice on designing web application with a 40+ year lifetime

  - by user2708395

  Scenario Currently, I am apart of a health care project whose main requirement is to capture data with unknown attributes using user generated forms by health care providers. The second requirement is that data integrity is key and that the application will be used for 40+ years. We are currently migrating the client's data from the past 40 years from various sources (Paper, Excel, Access, etc...) to the database. Future requirements are: Workflow management of forms Schedule management of forms Security/Role based management Reporting engine Mobile/Tablet support Situation Only 6 months in, the current (contracted) architect/senior programmer has taken the "fast" approach and has designed a poor system. The database is not normalized, the code is coupled, the tiers have no dedicated purpose and data is starting to go missing since he has designed some beans to perform "deletes" on the database. The code base is extremely bloated and there are jobs just to synchronize data since the database is not normalized. His approach has been to rely on backup jobs to restore missing data and doesn't seem to believe in re-factoring. Having presented my findings to the PM, the architect will be removed when his contract ends. I have been given the task to re-architect this application. My team consists of me and one junior programmer. We have no other resources. We have been granted a 6-month requirement freeze in which we can focus on re-building this system. I suggested using a CMS system like Drupal, but for policy reasons at the client's organization, the system must be built from scratch. This is the first time that I will be designing a system with a 40+ lifespan. I have only worked on projects with 3-5 year lifespans, so this situation is very new, yet exciting. Questions What design considerations will make the system more "future proof"? What experiences have you had in designing such systems - both failures and successes? What questions should be asked to the client/PM to make the system more "future proof"?

• Designing a system with different business rules for different customers

  - by user1595846

  My company is rewriting our proprietary business application. The current architecture is poorly done and inflexible. It is coded more procedural oriented as opposed to object oriented. It has become difficult to maintain. Our system is a web application written in .Net Webforms. I am considering ASP.Net MVC for the rewrite. We intend to rewrite it with a good, solid architecture with the goal of maintainability and reusable classes for some of our other systems and services. We would also like the system to be customizable for different customers in the event that we market the system. I am considering redesigning the system based on the layered architecture (Presentation, Business, Data Access layers) described in the Microsoft Patterns and Practices Application Architecture Guide. http://msdn.microsoft.com/en-us/library/ff650706.aspx Hopefully this isn't too open ended, but how would you recommend allowing for different business logic/rules for different customers? I'm aware of Windows Workflow Foundation, but from what I've read about it, it seems many business rules could be too complicated to handle there. Also, Can anyone point me to where I can download an example of a .net solution that is based on the Application Architecture Guide? I have already downloaded the Layered Architecture Solution Guidance and the Expense Sample on codeplex. I was looking for something a bit larger and more robust that I could step through the code and see how it works. If you feel there are better architectures to base our redesign on please feel free to share. I appreciate your help!

• 404s on password protected content

  - by tjb1982

  I'm new to WordPress and SEO, generally, but we've been running into problems with our site that don't seem to make sense to me. The problem is that our editor likes to schedule posts and/or mark them private until she is ready to make them public, but somehow Google is crawling these posts and getting 404s (because they are password protected). How does Google know they exist in the first place? I checked the sitemap.xml file and don't see a record of the post. One of the offending posts was marked public, but is scheduled for a future date. Could that have something to do with it? I've tried to Google the answer, and I came up with a good amount of reassurance that this won't hurt the site, but I'm still wondering how it's happening in the first place. It's hard because I don't know exactly what the editor's workflow is. Is it possible she's posting publicly first and then revising it to be private only after it's too late? Does anyone know how Google finds WordPress URLs it shouldn't have access to?

• List all BPM Processes for a user

  - by kasriniv

  Hello, Happy to start contributing to this blog..  The title of the blog is probably deceptively simple and warrants an elaboration. Customized BPM workspaces/user interfaces are a fairly common requirement. One of our marquee customers in the online stock trading business, envisioned this user interaction for their BPM application: User logs in to the internal portal Use will have list of roles which he is granted as a drop down list Once user selects the role, a list of processes which user is part of appear. Logged in user can be part of any swimlane role of the process This can be a fairly common/reasonable user-UI interaction pattern. 1. and 2. are easily achievable and hence the subject matter of this blog is the requirement in 3. Objective: Given a username and a role, list all the BPM processes that the user is part of, in any swimlane of any process. Here is quick overview of the major steps/logic in the code: Intialize workflow/BPM  context as usual Get a handle on InstanceQueryService(getInstanceQueryService), InstanceManagementService,        ProcessMetadataService and ProcessModelService List all Processes for that bpmcontext (listProcessMetadataSumary) and get Granted roles to that user For each of the processes [method  getAccessibleProcesss(ProcessMetadataSummary, Set)]for each of the lanes in the process, check if the role granted to the user, matches the roleName for that swimlane. If so, add to output. Notes: The usual caveats apply including BPM APIs are subject to change.  JDeveloper method introspection is your better friend than API documentation :-)... (I am going to try upload the source code  and if it doesnt work, will follow this blog up with the corresponding source code.) Hope this helps.  Ack: Yogesh K, BPM Dev team.

• How can I define custom keyboard mappings to resize, move, and manage windows?

  - by fumon

  I just returned to ubuntu (13.04) after a year using OS X exclusively. I love the improvements that have come to ubuntu and unity, and I'm glad to be back. There's just one thing, though... Slate is a simple OS X tool that allows users to quickly create powerful keyboard macros and really take advantage of their screen space. I have to say I was spoiled by it. Even on a tiny laptop, my workflow was never interrupted by changing workspaces or leaving the keyboard to adjust a window, because perfect adjustment was a keystroke or two away. For example: bind h:ctrl;alt;cmd resize -10% +0 # this increases the window's left width by 10% bind h:shift;alt nudge -10% +0 # this moves the window left by 10% You make a big config file, and like vim, tmux, and everything else, it just becomes muscle memory. I can't seem to find a way to achieve anything close to this in linux or ubuntu. I've tried to make do with compiz window settings and the built-in stuff Ubuntu offers, but it's not even in the same realm. Although to be fair, this level of tuning isn't something most people care about. Thanks, guys. :) Any feedback would be appreciated.

• How can I deal with a difficult developer that is holding back the project? [migrated]

  - by ILovePaperTowels

  Our entire project is being held up because of one piece which is being handled by a single developer. When we did finally got the latest version of his code and started reviewing it, we found the code was horrendous! Its a relatively simply workflow, however the code is so complex that it's very difficult to step through and review/debug. The developer responsible has a hard time accepting any kind of criticism, and feels he is more knowledgeable than others members of the team. It's difficult to even talk to him about his development work because it turns into "I know what I'm talking about and you're just wrong!" type of conversation. A request has already been put in to replace this developer but management is not doing anything. This is probably because devs are in short supply where we are, and this is a corporation has a lot of office drama. I'm just one of the developers, not the project manager, however I really want to see this project succeed. What can I do in this sort of situation to try and keep the project on track?

• Modular building technique with angles? (A roof)

  - by Mungoid

  Ive been spending a bit of time lately studying the modular buildings of many games and reading/viewing several tutorials about it as well, but almost every example I see uses a plain square building that does not have any angled roof or similar. In all my applications (CS6, Blender/Max, UDK) I adhere to the same grid spacing and I get pretty good results, but trying to make modular angled pieces is confusing me as I'm not sure the best way to approach it. Below is some shots of my template sheet and workflow I have been doing. Should I do the roof separately or is it possible for me to keep it in the same texture sheet? The main issue is below. I have made a couple modular roof pieces but when i try to use them, i end up needing to model multiple other parts to fill gaps based on what roof shape i want. I then model those 'filler' pieces and now i have that much less space left in my texture sheet and those pieces are usually not that reusable for anything else. This is where im not sure how to proceed. If anyone has any links to documents or papers talking about this or advice, I would greatly appreciate it! =-) My main roof pieces with the gaps My power of 2 texture sheet, with 16x16 grid squares. The texture sheet loaded into blender on a 16x16 plane and starting to separate and extrude.

• New: Online NetBeans 8 Crash Course

  - by Geertjan

  On Twitter today I came across an announcement for a brand new on-line course in NetBeans 8. Since NetBeans 8 has been released during the past few months, the course is really very new. Go here to get there directly: https://www.video2brain.com/de/videotraining/netbeans-ide-8-0-crashkurs Here's the general idea. As you can see, the course is in German. With my basic understanding of German, I've had no problem in following the course. The trainer speaks clearly and slowly and everything is very well structured. The course covers all the basics of NetBeans IDE. From getting set up to using all the key features. The quality of the videos is great and the content is clear and informative. Once you've bought the course, all the lessons are unlocked. As you can see, they're all quite short and there's really a lot of content, didn't all fit into the screenshot: Quite some work must have gone into this. Here's one of the free lessons in the course, to give an idea of what you'll get: https://www.video2brain.com/de/tutorial/texte-internationalisieren This one is also free: https://www.video2brain.com/de/tutorial/eclipse-projekt-importieren I highly recommend this course especially if you're switching, or thinking about switching, from a different IDE and want to get a thorough overview of all the features that NetBeans IDE provides. Everything in the course is done within NetBeans, which means no slides, just code. You get to see the workflow of all the standard tasks and, for these purposes, the course does a really great job.

• How to deal with bad developers who hold back the project

  - by ILovePaperTowels

  We're at the end of a project, but we continue to run into issues because of a single piece of the project. This piece is handled by a specific developer. Finally, we grabbed latest and started reviewing it. It's just horrendous code! Trying to step through it was difficult and it's a relatively simple workflow. The point of this question is, how to deal with this situation. The developer has a hard time accepting criticism (constructive or otherwise) and feels he is more knowledgeable than others on the team who are, well, highly decorated, experienced and accomplished developers. It's difficult to even get into a topic about development because it turns into "I know what I'm talking about and you're just wrong!" type of conversation. A request has already been put in to replace this developer but it is a hard sell since devs are in short supply where we are and this is a corporation with a LOT of political bs. Management has been notified a few times but nothing is happening.

  The final release of Visual Studio 2010 and .NET 4 is now available. Download and Install Today MSDN subscribers, as well as WebsiteSpark/BizSpark/DreamSpark members, can now download the final releases of Visual Studio 2010 and TFS 2010 through the MSDN subscribers download center.  If you are not an MSDN Subscriber, you can download free 90-day trial editions of Visual Studio 2010.  Or you can can download the free Visual Studio express editions of Visual Web Developer 2010, Visual Basic 2010, Visual C# 2010 and Visual C++.  These express editions are available completely for free (and never time out).  If you are looking for an easy way to setup a new machine for web-development you can automate installing ASP.NET 4, ASP.NET MVC 2, IIS, SQL Server Express and Visual Web Developer 2010 Express really quickly with the Microsoft Web Platform Installer (just click the install button on the page). What is new with VS 2010 and .NET 4 Today’s release is a big one – and brings with it a ton of new feature and capabilities. One of the things we tried hard to focus on with this release was to invest heavily in making existing applications, projects and developer experiences better.  What this means is that you don’t need to read 1000+ page books or spend time learning major new concepts in order to take advantage of the release.  There are literally thousands of improvements (both big and small) that make you more productive and successful without having to learn big new concepts in order to start using them.  Below is just a small sampling of some of the improvements with this release: Visual Studio 2010 IDE  Visual Studio 2010 now supports multiple-monitors (enabling much better use of screen real-estate).  It has new code Intellisense support that makes it easier to find and use classes and methods. It has improved code navigation support for searching code-bases and seeing how code is called and used.  It has new code visualization support that allows you to see the relationships across projects and classes within projects, as well as to automatically generate sequence diagrams to chart execution flow.  The editor now supports HTML and JavaScript snippet support as well as improved JavaScript intellisense. The VS 2010 Debugger and Profiling support is now much, much richer and enables new features like Intellitrace (aka Historical Debugging), debugging of Crash/Dump files, and better parallel debugging.  VS 2010’s multi-targeting support is now much richer, and enables you to use VS 2010 to target .NET 2, .NET 3, .NET 3.5 and .NET 4 applications.  And the infamous Add Reference dialog now loads much faster. TFS 2010 is now easy to setup (you can now install the server in under 10 minutes) and enables great source-control, bug/work-item tracking, and continuous integration support.  Testing (both automated and manual) is now much, much richer.  And VS 2010 Premium and Ultimate provide much richer architecture and design tooling support. VB and C# Language Features VB and C# in VS 2010 both contain a bunch of new features and capabilities.  VB adds new support for automatic properties, collection initializers, and implicit line continuation support among many other features.  C# adds support for optional parameters and named arguments, a new dynamic keyword, co-variance and contra-variance, and among many other features. ASP.NET 4 and ASP.NET MVC 2 With ASP.NET 4, Web Forms controls now render clean, semantically correct, and CSS friendly HTML markup. Built-in URL routing functionality allows you to expose clean, search engine friendly, URLs and increase the traffic to your Website.  ViewState within applications can now be more easily controlled and made smaller.  ASP.NET Dynamic Data support has been expanded.  More controls, including rich charting and data controls, are now built-into ASP.NET 4 and enable you to build applications even faster.  New starter project templates now make it easier to get going with new projects.  SEO enhancements make it easier to drive traffic to your public facing sites.  And web.config files are now clean and simple. ASP.NET MVC 2 is now built-into VS 2010 and ASP.NET 4, and provides a great way to build web sites and applications using a model-view-controller based pattern. ASP.NET MVC 2 adds features to easily enable client and server validation logic, provides new strongly-typed HTML and UI-scaffolding helper methods.  It also enables more modular/reusable applications.  The new <%: %> syntax in ASP.NET makes it easier to HTML encode output.  Visual Studio 2010 also now includes better tooling support for unit testing and TDD.  In particular, “Consume first intellisense” and “generate from usage" support within VS 2010 make it easier to write your unit tests first, and then drive your implementation from them. Deploying ASP.NET applications gets a lot easier with this release. You can now publish your Websites and applications to a staging or production server from within Visual Studio itself. Visual Studio 2010 makes it easy to transfer all your files, code, configuration, database schema and data in one complete package. VS 2010 also makes it easy to manage separate web.config configuration files settings depending upon whether you are in debug, release, staging or production modes. WPF 4 and Silverlight 4 WPF 4 includes a ton of new improvements and capabilities including more built-in controls, richer graphics features (cached composition, pixel shader 3 support, layoutrounding, and animation easing functions), a much improved text stack (with crisper text rendering, custom dictionary support, and selection and caret brush options).  WPF 4 also includes a bunch of support to enable you to take advantage of new Windows 7 features – including multi-touch and Windows 7 shell integration. Silverlight 4 will launch this week as well.  You can watch my Silverlight 4 launch keynote streamed live Tuesday (April 13th) at 8am Pacific Time.  Silverlight 4 includes a ton of new capabilities – including a bunch for making it possible to build great business applications and out of the browser applications.  I’ll be doing a separate blog post later this week (once it is live on the web) that talks more about its capabilities. Visual Studio 2010 now includes great tooling support for both WPF and Silverlight.  The new VS 2010 WPF and Silverlight designer makes it much easier to build client applications as well as build great line of business solutions, as well as integrate and bind with data.  Tooling support for Silverlight 4 with the final release of Visual Studio 2010 will be available when Silverlight 4 releases to the web this week. SharePoint and Azure Visual Studio 2010 now includes built-in support for building SharePoint applications.  You can now create, edit, build, and debug SharePoint applications directly within Visual Studio 2010.  You can also now use SharePoint with TFS 2010. Support for creating Azure-hosted applications is also now included with VS 2010 – allowing you to build ASP.NET and WCF based applications and host them within the cloud. Data Access Data access has a lot of improvements coming to it with .NET 4.  Entity Framework 4 includes a ton of new features and capabilities – including support for model first and POCO development, default support for lazy loading, built-in support for pluralization/singularization of table/property names within the VS 2010 designer, full support for all the LINQ operators, the ability to optionally expose foreign keys on model objects (useful for some stateless web scenarios), disconnected API support to better handle N-Tier and stateless web scenarios, and T4 template customization support within VS 2010 to allow you to customize and automate how code is generated for you by the data designer.  In addition to improvements with the Entity Framework, LINQ to SQL with .NET 4 also includes a bunch of nice improvements.  WCF and Workflow WCF includes a bunch of great new capabilities – including better REST, activation and configuration support.  WCF Data Services (formerly known as Astoria) and WCF RIA Services also now enable you to easily expose and work with data from remote clients. Windows Workflow is now much faster, includes flowchart services, and now makes it easier to make custom services than before.  More details can be found here. CLR and Core .NET Library Improvements .NET 4 includes the new CLR 4 engine – which includes a lot of nice performance and feature improvements.  CLR 4 engine now runs side-by-side in-process with older versions of the CLR – allowing you to use two different versions of .NET within the same process.  It also includes improved COM interop support.  The .NET 4 base class libraries (BCL) include a bunch of nice additions and refinements.  In particular, the .NET 4 BCL now includes new parallel programming support that makes it much easier to build applications that take advantage of multiple CPUs and cores on a computer.  This work dove-tails nicely with the new VS 2010 parallel debugger (making it much easier to debug parallel applications), as well as the new F# functional language support now included in the VS 2010 IDE.  .NET 4 also now also has the Dynamic Language Runtime (DLR) library built-in – which makes it easier to use dynamic language functionality with .NET.  MEF – a really cool library that enables rich extensibility – is also now built-into .NET 4 and included as part of the base class libraries.  .NET 4 Client Profile The download size of the .NET 4 redist is now much smaller than it was before (the x86 full .NET 4 package is about 36MB).  We also now have a .NET 4 Client Profile package which is a pure sub-set of the full .NET that can be used to streamline client application installs. C++ VS 2010 includes a bunch of great improvements for C++ development.  This includes better C++ Intellisense support, MSBuild support for projects, improved parallel debugging and profiler support, MFC improvements, and a number of language features and compiler optimizations. My VS 2010 and .NET 4 Blog Series I’ve been cranking away on a blog series the last few months that highlights many of the new VS 2010 and .NET 4 improvements.  The good news is that I have about 20 in-depth posts already written.  The bad news (for me) is that I have about 200 more to go until I’m done!  I’m going to try and keep adding a few more each week over the next few months to discuss the new improvements and how best to take advantage of them. Below is a list of the already written ones that you can check out today: Clean Web.Config Files Starter Project Templates Multi-targeting Multiple Monitor Support New Code Focused Web Profile Option HTML / ASP.NET / JavaScript Code Snippets Auto-Start ASP.NET Applications URL Routing with ASP.NET 4 Web Forms Searching and Navigating Code in VS 2010 VS 2010 Code Intellisense Improvements WPF 4 Add Reference Dialog Improvements SEO Improvements with ASP.NET 4 Output Cache Extensibility with ASP.NET 4 Built-in Charting Controls for ASP.NET and Windows Forms Cleaner HTML Markup with ASP.NET 4 - Client IDs Optional Parameters and Named Arguments in C# 4 - and a cool scenarios with ASP.NET MVC 2 Automatic Properties, Collection Initializers and Implicit Line Continuation Support with VB 2010 New <%: %> Syntax for HTML Encoding Output using ASP.NET 4 JavaScript Intellisense Improvements with VS 2010 Stay tuned to my blog as I post more.  Also check out this page which links to a bunch of great articles and videos done by others. VS 2010 Installation Notes If you have installed a previous version of VS 2010 on your machine (either the beta or the RC) you must first uninstall it before installing the final VS 2010 release.  I also recommend uninstalling .NET 4 betas (including both the client and full .NET 4 installs) as well as the other installs that come with VS 2010 (e.g. ASP.NET MVC 2 preview builds, etc).  The uninstalls of the betas/RCs will clean up all the old state on your machine – after which you can install the final VS 2010 version and should have everything just work (this is what I’ve done on all of my machines and I haven’t had any problems). The VS 2010 and .NET 4 installs add a bunch of new managed assemblies to your machine.  Some of these will be “NGEN’d” to native code during the actual install process (making them run fast).  To avoid adding too much time to VS setup, though, we don’t NGEN all assemblies immediately – and instead will NGEN the rest in the background when your machine is idle.  Until it finishes NGENing the assemblies they will be JIT’d to native code the first time they are used in a process – which for large assemblies can sometimes cause a slight performance hit. If you run into this you can manually force all assemblies to be NGEN’d to native code immediately (and not just wait till the machine is idle) by launching the Visual Studio command line prompt from the Windows Start Menu (Microsoft Visual Studio 2010->Visual Studio Tools->Visual Studio Command Prompt).  Within the command prompt type “Ngen executequeueditems” – this will cause everything to be NGEN’d immediately. How to Buy Visual Studio 2010 You can can download and use the free Visual Studio express editions of Visual Web Developer 2010, Visual Basic 2010, Visual C# 2010 and Visual C++.  These express editions are available completely for free (and never time out). You can buy a new copy of VS 2010 Professional that includes a 1 year subscription to MSDN Essentials for $799.  MSDN Essentials includes a developer license of Windows 7 Ultimate, Windows Server 2008 R2 Enterprise, SQL Server 2008 DataCenter R2, and 20 hours of Azure hosting time.  Subscribers also have access to MSDN’s Online Concierge, and Priority Support in MSDN Forums. Upgrade prices from previous releases of Visual Studio are also available.  Existing Visual Studio 2005/2008 Standard customers can upgrade to Visual Studio 2010 Professional for a special $299 retail price until October.  You can take advantage of this VS Standard->Professional upgrade promotion here. Web developers who build applications for others, and who are either independent developers or who work for companies with less than 10 employees, can also optionally take advantage of the Microsoft WebSiteSpark program.  This program gives you three copies of Visual Studio 2010 Professional, 1 copy of Expression Studio, and 4 CPU licenses of both Windows 2008 R2 Web Server and SQL 2008 Web Edition that you can use to both develop and deploy applications with at no cost for 3 years.  At the end of the 3 years there is no obligation to buy anything.  You can sign-up for WebSiteSpark today in under 5 minutes – and immediately have access to the products to download. Summary Today’s release is a big one – and has a bunch of improvements for pretty much every developer.  Thank you everyone who provided feedback, suggestions and reported bugs throughout the development process – we couldn’t have delivered it without you.  Hope this helps, Scott P.S.

• Announcing Entity Framework Code-First (CTP5 release)

  - by ScottGu

  This week the data team released the CTP5 build of the new Entity Framework Code-First library.  EF Code-First enables a pretty sweet code-centric development workflow for working with data.  It enables you to: Develop without ever having to open a designer or define an XML mapping file Define model objects by simply writing “plain old classes” with no base classes required Use a “convention over configuration” approach that enables database persistence without explicitly configuring anything Optionally override the convention-based persistence and use a fluent code API to fully customize the persistence mapping I’m a big fan of the EF Code-First approach, and wrote several blog posts about it this summer: Code-First Development with Entity Framework 4 (July 16th) EF Code-First: Custom Database Schema Mapping (July 23rd) Using EF Code-First with an Existing Database (August 3rd) Today’s new CTP5 release delivers several nice improvements over the CTP4 build, and will be the last preview build of Code First before the final release of it.  We will ship the final EF Code First release in the first quarter of next year (Q1 of 2011).  It works with all .NET application types (including both ASP.NET Web Forms and ASP.NET MVC projects). Installing EF Code First You can install and use EF Code First CTP5 using one of two ways: Approach 1) By downloading and running a setup program.  Once installed you can reference the EntityFramework.dll assembly it provides within your projects.      or: Approach 2) By using the NuGet Package Manager within Visual Studio to download and install EF Code First within a project.  To do this, simply bring up the NuGet Package Manager Console within Visual Studio (View->Other Windows->Package Manager Console) and type “Install-Package EFCodeFirst”: Typing “Install-Package EFCodeFirst” within the Package Manager Console will cause NuGet to download the EF Code First package, and add it to your current project: Doing this will automatically add a reference to the EntityFramework.dll assembly to your project:   NuGet enables you to have EF Code First setup and ready to use within seconds.  When the final release of EF Code First ships you’ll also be able to just type “Update-Package EFCodeFirst” to update your existing projects to use the final release. EF Code First Assembly and Namespace The CTP5 release of EF Code First has an updated assembly name, and new .NET namespace: Assembly Name: EntityFramework.dll Namespace: System.Data.Entity These names match what we plan to use for the final release of the library. Nice New CTP5 Improvements The new CTP5 release of EF Code First contains a bunch of nice improvements and refinements. Some of the highlights include: Better support for Existing Databases Built-in Model-Level Validation and DataAnnotation Support Fluent API Improvements Pluggable Conventions Support New Change Tracking API Improved Concurrency Conflict Resolution Raw SQL Query/Command Support The rest of this blog post contains some more details about a few of the above changes. Better Support for Existing Databases EF Code First makes it really easy to create model layers that work against existing databases.  CTP5 includes some refinements that further streamline the developer workflow for this scenario. Below are the steps to use EF Code First to create a model layer for the Northwind sample database: Step 1: Create Model Classes and a DbContext class Below is all of the code necessary to implement a simple model layer using EF Code First that goes against the Northwind database: EF Code First enables you to use “POCO” – Plain Old CLR Objects – to represent entities within a database.  This means that you do not need to derive model classes from a base class, nor implement any interfaces or data persistence attributes on them.  This enables the model classes to be kept clean, easily testable, and “persistence ignorant”.  The Product and Category classes above are examples of POCO model classes. EF Code First enables you to easily connect your POCO model classes to a database by creating a “DbContext” class that exposes public properties that map to the tables within a database.  The Northwind class above illustrates how this can be done.  It is mapping our Product and Category classes to the “Products” and “Categories” tables within the database.  The properties within the Product and Category classes in turn map to the columns within the Products and Categories tables – and each instance of a Product/Category object maps to a row within the tables. The above code is all of the code required to create our model and data access layer!  Previous CTPs of EF Code First required an additional step to work against existing databases (a call to Database.Initializer<Northwind>(null) to tell EF Code First to not create the database) – this step is no longer required with the CTP5 release.  Step 2: Configure the Database Connection String We’ve written all of the code we need to write to define our model layer.  Our last step before we use it will be to setup a connection-string that connects it with our database.  To do this we’ll add a “Northwind” connection-string to our web.config file (or App.Config for client apps) like so:   <connectionStrings>          <add name="Northwind"          connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\northwind.mdf;User Instance=true"          providerName="System.Data.SqlClient" />   </connectionStrings> EF “code first” uses a convention where DbContext classes by default look for a connection-string that has the same name as the context class.  Because our DbContext class is called “Northwind” it by default looks for a “Northwind” connection-string to use.  Above our Northwind connection-string is configured to use a local SQL Express database (stored within the \App_Data directory of our project).  You can alternatively point it at a remote SQL Server. Step 3: Using our Northwind Model Layer We can now easily query and update our database using the strongly-typed model layer we just built with EF Code First. The code example below demonstrates how to use LINQ to query for products within a specific product category.  This query returns back a sequence of strongly-typed Product objects that match the search criteria: The code example below demonstrates how we can retrieve a specific Product object, update two of its properties, and then save the changes back to the database: EF Code First handles all of the change-tracking and data persistence work for us, and allows us to focus on our application and business logic as opposed to having to worry about data access plumbing. Built-in Model Validation EF Code First allows you to use any validation approach you want when implementing business rules with your model layer.  This enables a great deal of flexibility and power. Starting with this week’s CTP5 release, EF Code First also now includes built-in support for both the DataAnnotation and IValidatorObject validation support built-into .NET 4.  This enables you to easily implement validation rules on your models, and have these rules automatically be enforced by EF Code First whenever you save your model layer.  It provides a very convenient “out of the box” way to enable validation within your applications. Applying DataAnnotations to our Northwind Model The code example below demonstrates how we could add some declarative validation rules to two of the properties of our “Product” model: We are using the [Required] and [Range] attributes above.  These validation attributes live within the System.ComponentModel.DataAnnotations namespace that is built-into .NET 4, and can be used independently of EF.  The error messages specified on them can either be explicitly defined (like above) – or retrieved from resource files (which makes localizing applications easy). Validation Enforcement on SaveChanges() EF Code-First (starting with CTP5) now automatically applies and enforces DataAnnotation rules when a model object is updated or saved.  You do not need to write any code to enforce this – this support is now enabled by default.  This new support means that the below code – which violates our above rules – will automatically throw an exception when we call the “SaveChanges()” method on our Northwind DbContext: The DbEntityValidationException that is raised when the SaveChanges() method is invoked contains a “EntityValidationErrors” property that you can use to retrieve the list of all validation errors that occurred when the model was trying to save.  This enables you to easily guide the user on how to fix them.  Note that EF Code-First will abort the entire transaction of changes if a validation rule is violated – ensuring that our database is always kept in a valid, consistent state. EF Code First’s validation enforcement works both for the built-in .NET DataAnnotation attributes (like Required, Range, RegularExpression, StringLength, etc), as well as for any custom validation rule you create by sub-classing the System.ComponentModel.DataAnnotations.ValidationAttribute base class. UI Validation Support A lot of our UI frameworks in .NET also provide support for DataAnnotation-based validation rules. For example, ASP.NET MVC, ASP.NET Dynamic Data, and Silverlight (via WCF RIA Services) all provide support for displaying client-side validation UI that honor the DataAnnotation rules applied to model objects. The screen-shot below demonstrates how using the default “Add-View” scaffold template within an ASP.NET MVC 3 application will cause appropriate validation error messages to be displayed if appropriate values are not provided: ASP.NET MVC 3 supports both client-side and server-side enforcement of these validation rules.  The error messages displayed are automatically picked up from the declarative validation attributes – eliminating the need for you to write any custom code to display them. Keeping things DRY The “DRY Principle” stands for “Do Not Repeat Yourself”, and is a best practice that recommends that you avoid duplicating logic/configuration/code in multiple places across your application, and instead specify it only once and have it apply everywhere. EF Code First CTP5 now enables you to apply declarative DataAnnotation validations on your model classes (and specify them only once) and then have the validation logic be enforced (and corresponding error messages displayed) across all applications scenarios – including within controllers, views, client-side scripts, and for any custom code that updates and manipulates model classes. This makes it much easier to build good applications with clean code, and to build applications that can rapidly iterate and evolve. Other EF Code First Improvements New to CTP5 EF Code First CTP5 includes a bunch of other improvements as well.  Below are a few short descriptions of some of them: Fluent API Improvements EF Code First allows you to override an “OnModelCreating()” method on the DbContext class to further refine/override the schema mapping rules used to map model classes to underlying database schema.  CTP5 includes some refinements to the ModelBuilder class that is passed to this method which can make defining mapping rules cleaner and more concise.  The ADO.NET Team blogged some samples of how to do this here. Pluggable Conventions Support EF Code First CTP5 provides new support that allows you to override the “default conventions” that EF Code First honors, and optionally replace them with your own set of conventions. New Change Tracking API EF Code First CTP5 exposes a new set of change tracking information that enables you to access Original, Current & Stored values, and State (e.g. Added, Unchanged, Modified, Deleted).  This support is useful in a variety of scenarios. Improved Concurrency Conflict Resolution EF Code First CTP5 provides better exception messages that allow access to the affected object instance and the ability to resolve conflicts using current, original and database values.  Raw SQL Query/Command Support EF Code First CTP5 now allows raw SQL queries and commands (including SPROCs) to be executed via the SqlQuery and SqlCommand methods exposed off of the DbContext.Database property.  The results of these method calls can be materialized into object instances that can be optionally change-tracked by the DbContext.  This is useful for a variety of advanced scenarios. Full Data Annotations Support EF Code First CTP5 now supports all standard DataAnnotations within .NET, and can use them both to perform validation as well as to automatically create the appropriate database schema when EF Code First is used in a database creation scenario.  Summary EF Code First provides an elegant and powerful way to work with data.  I really like it because it is extremely clean and supports best practices, while also enabling solutions to be implemented very, very rapidly.  The code-only approach of the library means that model layers end up being flexible and easy to customize. This week’s CTP5 release further refines EF Code First and helps ensure that it will be really sweet when it ships early next year.  I recommend using NuGet to install and give it a try today.  I think you’ll be pleasantly surprised by how awesome it is. Hope this helps, Scott
