CilAssemblyNotFoundException

I've just loaded a project up for the first time and I get the following stack trace in ncrunch.

Can anyone direct me in to how to fix this?

Hi, thanks for sharing this issue.

Can you confirm if setting your 'Framework utilisation type for MSTest' to 'DynamicAnalysis' works around the problem?

Thank you that worked. I knew there would be a setting somewhere I just couldn't find it.

Thanks for confirming this. We do have a fix pending for this issue which will be out with the next release. I'd suggest staying with DynamicAnalysis for now.
