Please note that I am following along on this course, and am presently in module 5: https://www.pluralsight.com/courses/wcf-end-to-end

The problem is that I am trying to run the unit tests, but every time I do I get the above error. Here is the full stack trace:

I can get it to work with NUnit, but if I switch the project to MsTest then I get the above error. Please note that I have researched various posts like the following but have not resolved the error:

VS2017 Could not load file or assembly Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll or one of its dependencies

Does anyone have any suggestions?

CodePudding user response：

It appears that Microsoft changed some assemblies/namespaces among other things for their unit testing framework and somehow broke something or there may be a problem with ReSharper so I ended up sticking with NUnit.
