Unable to obtain public key for StrongNameKeyPair.

Hi,

Since moving to VS2010 I seem to have gotten the "Unable to obtain public key for StrongNameKeyPair" error trying to mock and interface.

I am running VS2010, .Net 4.0, Typemock 6.0.3.0 MBUbit/Gallio. All are x64 flavour. I am running as Admin.

Code and call stack below. This happend to me last year too.

Yell if you need any other info.

Cheers
Bart

Code to repro.

using MbUnit.Framework;
using TypeMock.ArrangeActAssert;

namespace ClassLibrary1
{
[Isolated]
[TestFixture]
public class Class1
{
[Test] public void TestInterface() { var x = Isolate.Fake.Instance<IMyInterface>(); } // FAIL
[Test] public void TestClass() { var x = Isolate.Fake.Instance<MyClass>(); } // PASS
}

public interface IMyInterface { }
public class MyClass { }
}


This is the stack running the test.
