WPF applications do not works after .NET 3.5 Beta 2 installing

After I installed .NET 3.5 Beta 2 and Visual Studio 2008 Team System Beta 2 my WPF applications do not works! For example: Expression Blend, Blend 2 Aug Preview and Expression Design. I now can't use these softwares and I can't write WPF programs. Error message: "XXX has stopped working.". I use Windows Vista Ultimate x86.

So VS beta2 works but now express does not work?

Do you have any WPF apps on your machine that do work after the install?

Also, which exact versions of the Blend and Express toosl do you have, are they all from the same preview?

Thanks. -Bret

VS 2008 Beta 2 WPF designer does not work.

My WPF apps don't work. Neither.

I have a retail Expression Studio and a Expression Blend 2 Aug Preview.

I tried to debug my programs, the result:

An unhandled exception of type 'System.TypeLoadException' occurred in PresentationFramework.dll

Additional information: Could not load type 'MS.Internal.WpfWebRequestHelper' from assembly 'PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

The same goes by me.

Just installed VS 2008 C# Express Editon BETA 2 and created a new WPF project from the project template.

Designer couldn't load the Windows xaml file and after attempting to run the project following exception occured :

Der Typ MS.Internal.WpfWebRequestHelper in der Assembly PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 konnte nicht geladen werden.

I've looked into the PresentationCore Assembly and couldn't find this type.

I'm running VISTA Home Premium.

Formerly running BETA1 hopefully correct deinstalled.

Appreciate any help. Thanks in advance

I see the same problem.

I am also on Vista Home Premium.

I install Visual Studio 2008 Professional Beta 2. (I had the same problem with Visual Studio C# Express Beta2)

I didn't have Beta 1.

I solved this problem! The problem source is the KB925255 Windows update. If you remove this update the WPF applications will work fine.

Thanks!!!!

Uninstalling KB925255 fixed my system too.

I have this problem in an Windows XP SP2 system and the KB just seems to be for Vista.

Anyone knows how to fix this?

I also have Visual Studio 2005 SP1 with the November CTP of the Cider installed.
