title: Could not load file or assembly NUnit
body: <p>We have a C# application written in C# and recently switched over from MbUnit to NUnit, I am the only one with an issue where upon running any tests I get a Could not load file or assembly exception for every test. The test seems to start up fine but a call to OpenMappedExeConfiguration is failing even though the path and filename are correct. I'm out of ideas as I have done a clean checkout of the codebase and I still get the same issue.</p>
