I installed Visual Studio 2010 Beta 2 in an XP Mode VM on Windows 7. Then I created a trivial Silverlight 4 (beta) project and tried to build it. I get the following error:
Error 1 The "ValidateXaml" task failed
unexpectedly.
System.IO.FileLoadException: Could not

--- System.NotSupportedException: An attempt was made to load an assembly

I believe this is related to the fact that XP Mode redirects the My Documents folder to the host, turning it into a network share location, and some sort of CAS / security policy is being triggered.
Anyone know how to fix it?
