Ok, at first sight the error Unable to load one or more of the requested type occurs when invoking the Test Method.

Now, a couple of questions:

  1. Is this running on Windows, or Mono on another platform?
  2. If you download the example solution, and make no changes, does that execute tests correctly?
  3. Can you supply an example of the code you are attempting to test so I can debug this?

  1. It is running on Windows...
  2. I haven't tested downloading the solutions, but for exact copied code problem still exists. I'll try downloading the solutions.
  3. Sorry, this is part of my work code, I'll see if I can provide similar code.

Ok, thanks.. I would first suggest trying the supplied sample project. If that gives you the same error that is easier for me to investigate.

Something did occur to me - an instance of the Test to be executed is created using a Dynamic Method Delegates. In the current implementation. the creation of this Delegate is currently limited to have three parameters, which is a reasonable number for a Test. It would fail if the Test has more, but I would have expected a different error message if this was the case...

I have closed this, as I have not heard back regarding whether the sample project is functional for you. If you have further information, please feel free to supply it, and I will investigate.
