ShimNotSupportedException in MS VisualStudio 2012

Question

I\'m just trying to get familiar with the new Fakes Isolation Framework in Visual Studio 2012 RC but I\'m consequently facing issues with ShimNotSupportedException

Answer 1

I have seen this error a number of times with different causes:

• There is an error or problem in your fakes generation files, some of them are not correct generated. Clean the directories and remake your fake references
• A depending dll is missing. In this case you are missing a dll on which a fakes dll depends. In one case I was shimming a webservice and missing the System.ServiceModel dll.
• Sometimes you can fix it with changing your testsetting default processor architecure. However I do not know why, it will probably refresh some cached dlls.
