Hi, thanks for sharing this issue. I've immediately managed to reproduce it as you've described.
It looks as though this is specific to NCrunch's static analysis method. I'm not sure yet where the issue lies but will do my best to have it fixed for the release build of 2.11.
Meanwhile, you should be able to work around the problem by changing your 'Framework utilisation type for XUnit V2+' to 'DynamicAnalysis'. This is an NCrunch solution-level configuration setting.
