I've created a very simple example in VS.NET 2008, then I converted the project to VS.NET 2010 and ran it - it runs just fine. However, when I opened up the Window1.xaml in the designer I get the following:
System.Reflection.TargetInvocationException
Exception has been thrown by the target of an invocation.
