If you are seeing this exception (MockTypes.MockTypeGenerator) and have the target platform set to X64 or ARM, try switching to X86 and rebuilding.

Since we can't run project code in X64 or ARM, we attempt to provide a set of mock types based on your code. We are adding additional warnings in future updates of Visual Studio.
