I think I completed the tasks, but still the unit tests do not run. "Could not find dependent assembly..."

Does the solution successfully build?

Yes, only the unit tests are not running.

What extensions do you have installed?

Looking more closely at the output warnings, it looks like there are two versions of the Xunit VS test runner installed. Is there a chance that one of the other projects in the solution has the Xunit VS test runner NuGet package installed?

Here's an issue on GitHub that provides some additional information about this issue: https://github.com/xunit/xunit/issues/1542

Have you had any luck on resolving this issue?

I did not resolve the issue, but after uploading the projects, they passed the tests and I managed to complete the course without any issue.

Sorry to hear that the issue is still present, but I'm glad that you were able to complete the course regardless.

Thanks ~James

Thank you, James, for your support.
