I don’t know why, but the tests in one assembly suddenly stopped working.

An error occurred while analysing this project after it was built: NUnit failed to discover the tests in this assembly: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
----> Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
----> Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

I’m not sure where to investigate. The tests run as expected in Rider and Visual Studio, but they do not work in NCrunch.

As far as I can tell, nothing changed on the build server. O:-)


Logs are too long for a chat, so i trimmed some lines....
