Question

I seem to be unable to run any unit test. All the errors are along following lines:

    Test method TvQueue.UnitTesting.TheTvDb.TheTvDbServiceTest.GetShowbasicTest threw exception:

I get this problem when developing Windows Phone 8 code. For some reason, MSTest wants to load older versions of assemblies (the assemblies actually referenced in the project are 4.x or higher, MSTest wants to load 2.x versions).

I suspect this is a configuration issue, but I have no idea how to fix it.

Thanks for helping out.

Answer 1

Please see my answer on How to use MSTest in VS2010 for Windows Phone 8 applications

the assemblies actually referenced in the project are 4.x or higher

System.Windows, Version=2.0.6.0 isn’t a old version, it’s the correct new version. And you can’t actually see the version number of the individual assemblies, are there are no such thing as individual assemblies.

Remember the main change is that Windows Phone 8, like Windows RT, no longer uses direct assemblies, but WinMD files that compiles several assemblies into a single API.
