Hi, thanks for posting.

One way I could think of solving this is to introduce an assembly reference to each of the required DLLs from the test projects being used by NCrunch that need to have them in the working directory. If you turn on the 'Copy referenced assemblies to workspace' setting for these test projects (and probably for the other projects too), NCrunch should make sure the DLLs are sitting in the runtime directory of each test project, allowing the assemblies to resolve at runtime.
