NUnit and Windows Phone Library (System.TypeLoadException)

Question

I am trying to test a Windows Phone 7.1 class library with NUnit and the standard console (GUI or not GUI) runner.

After my problem, related below I have found this one: http://dotneteers.net/blogs/vbandi/archive/2012/08/08/using-nunit-to-test-windows-phone-7-applications-part-1.aspx

So I am almost sure this is a silly problem at my own.

Every time I try to load my assembly testing I get this error:

System.TypeLoadException: Cannot load type 'System.Runtime.Versioning.TargetFrameworkAttribute' from assembly'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

For futher information, use the Exception Details menu item.

Somebody know what is the problem I'm not be able to find ?

Answer 1

I have found (in a very easy to explain way) what is the problem and what is the solution (or better said the alternative).

The problem is that NUnit Console Runner (or GUI runner), execute under a different environment. I mean a Console Application or a Winforms application and then they try to load a Windows Phone library and that is the problem.

The solution is execute the tests with Re-Sharper, NCrunch, Visual NUnit or something similar and NOT use NUnit default runners.

I'm using Visual NUnit. http://visualstudiogallery.msdn.microsoft.com/c8164c71-0836-4471-80ce-633383031099
