Lance,
The workaround will work, but I really want to solve the problem.
We test that TypeMock works on the Professional version, so I guess that it is something else.
Please send me your Visual Studio Configuration. Here is how:
:arrow: In Visual Studio->Help->About Visual Studio->Click Copy Info
Then paste it into a post
:?: As we are currently developing the mscorlib mocks, could you tell me what class you needed to mock.
