Microsoft.Windows.Design.Extensibility 3.8 not found

 Hi,

When I try to build my silverlight application in Expression Blend 3 Beta it shows the following error message for each .xaml file
in my project.

"The file or assembly "Microsoft.Windows.Design.Extensibility, Version=3.8.0.0, Culture=neutral, PublicKeyToken=b03f5f711d50a3a"
or one of its dependencies was not found. The located assembly's manifest definition does not match the assembly reference.
(Exception from HRESULT: 0x80131040)"

I did not add a reference to "Microsoft.Windows.Design.Extensibility" to my project.

I've looked into "C:\Windows\assembly" and there are only versions 3.5 and 3.7 of "Microsoft.Windows.Design.Extensibility".

Has anybody an idea why blend thinks that this dll is needed or where I get the specified version (3.8)?

Hi,

I chose "Silverlight 3 Application + Website" when I created the project.

After some changes to the project, this error occurred. Somehow it seems that I have told it to include this dll (although I don't need / want it to be included in my project).

Has anybody an Idea how I can find out where this dll is included? (I've searched in the project files, but it is not referenced there anywhere)
