Hello.

I'm using NCrunch v3.14.0.1

I have a .NET project which Visual Studio is building without a hitch. However, when NCrunch is doing it's own build of the solution, the following error appears in the NCrunch Test window:

I have used previous versions of NCrunch with this same solution, and that worked fine regards test discovery and building. I think the problem started with this specific version, but I'm not 100% sure.

Thanks.

Hi, thanks for posting.

This is probably a limitation from the use of static analysis when discovering MSTest DataRow tests. Transferring some types from the static domain into a dynamic one for runtime can sometimes be problematic. I'd suggest changing your 'Framework utilisation type for MSTest' setting to 'DynamicAnalysis' for better compatibility with these framework features.
