Visual Studio 2005 SP1 released - details about changes for web tools

  • Comments 30

As many of you may heard Visual Studio 2005 SP1 was officially released several days ago.  There have already been a couple of blog posts announcing the release from ScottGu and Soma.  One item of feedback I saw on those posts was a request for more information about the actual fixes in SP1.

I'm writing this blog post to provide more information about the SP1 fixes in the "web tools" area -- specifically those pieces of Visual Studio 2005 and Visual Web Developer 2005 Express used to target ASP.NET.  I'll also include a list of bug fixes we made to "web tools" so people can have more detail into what was fixed.  NOTE: the information here only pertains to "web tools" in Visual Studio 2005, and does not represent everything that was fixed in SP1 (there were many other bug fixes in parts of Visual Studio outside of "web tools").

If anyone out there is using Visual Studio 2005 or Visual Web Developer 2005 Express to do ASP.NET development, I highly recommend installing SP1.  With SP1 you get the following big benefits for ASP.NET development (I'll cover each in more detail below):

  1. Addition of Web Application Projects feature (note - does not apply to Visual Web Developer 2005 Express)
  2. Improvements to performance of ASP.NET features in the IDE
  3. Bug fixes to many customer reported issues
  4. Changes to enable support for ASP.NET AJAX scenarios

1. Addition of Web Applicaiton Projects

Web Application Projects is a new feature that is made available in Visual Studio 2005 SP1.  Web Application Projects uses a project-file just like Visual Studio 2003 web projects, and provides most of the same functionality available in web projects in Visual Studio 2003.  If you are converting a web project from Visual Studio 2003, Web Application Projects makes the conversion pretty much seamless.  If you would like to know more about this new feature, there is much more detailed information about Web Application Projects here.

2. Improvements to performance of ASP.NET features in the IDE

SP1 has several improvements to increase performance of the Visual Studio IDE when doing ASP.NET development. 

  • The most noticeble improvement to customers will likely be when editing ASPX pages in "source" view.  Rather than re-stating everything we've done here, I'll link instead to this great post from ScottGu describing all the things we do to make ASPX editing faster in SP1.
  • Improved IDE performance when a very large number files exist in the \bin folder of your application.
  • Improved initial loading time of built-in Visual Studio development server.
  • Fixed memory leak when using Wizard inside a View or MultiView control.
  • Open XML file with links to external files was very slow.  This has been fixed.

I also highly recommend that people read ScottGu's more general blog post about performance tuning the IDE for ASP.NET development here.

3. Bug Fixes

Below is the list of bug fixes we made in the "web tools" area in Visual Studio 2005 SP1.  Once again, please remember, these are only fixes to "web tools" and do not represent all of the fixes in SP1.

Bugs found during internal testing:

4. Changes to enable support for ASP.NET AJAX

Finally, SP1 also has some bug fixes that enable much better support for editing pages with ASP.NET AJAX syntax in Visual Studio 2005.  Specifically, it addresses issues of incorrect validation of markup in the "source" view of content pages when using ASP.NET AJAX controls.  Also, SP1 fixes scenarios where pages using ASP.NET AJAX syntax would lose formatting when switching between source and design view.


I hope the information provided here will help users get a more detailed picture of some of the things that are fixed in SP1.  I'll also re-iterate that if you are doing ASP.NET development using Visual Studio 2005, I highly recommend installing SP1.  Looking forward to your comments, cheers!

  • Thanks, we were very curious about improvements in SP1. I specially like improved performance of Refactoring.

  • If you are an ASP.NET AJAX developer, I recommend you grab SP1 of VS2005… Not only does it include tons

  • Thanks for this post Omar.  This sort of thing is very important in my book so that companies can make a more educated decision to apply the patch.

    Great job collating this all together.

  • I installed SP1 - now the Web Application Projects fail to load - VS thinks fora few minutes and then does a quick exit - any suggestions?

  • After reinstalling a 2nd time (it did install the first time) it started finding the projects - the PC is runninh Win XP Media Center with all updates.

  • Can web site that use javascript be tested using SP1? Per MS support, VS2005's testing tools will not work with web site that use javascript.


  • Hello TB,

    The testing tools in Visual Studio 2005 work with managed code (e.g. - VB / C#).  VS 2005 also has a web recorder that allows you to create automated web tests from a browser to do load testing on the server.  Specifically the JavaScript code that runs in the browser cannot be tested in an automated fashion using VS2005, however the rest of the application can still be tested in an automated manner.  Hope this helps.
