How to get Code Coverage working on a VS 2010 project?

Question

When I turn on Code Coverage in my test settings, on a project that references the Unity DI container I get the following error:

Cannot initialize the ASP.NET project '{Project Name}'.

The event log specifies the following reason:

Could not load file or assembly 'Microsoft.Practices.Unity, Version=2.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. Strong name signature could not be verified.

How do I get around this issue?

I am running Visual Studio 2010 Ultimate on a Windows 7 X64 machine.

Answer 1

How do I get around this issue?

A shot in the dark without knowing the root cause: Have you tried using the strong name utility to skip verification of the offending assembly(s)?

sn -Vr <assembly>

Answer 2

I've had the exact same problem (although with Ninject) - see the second error in my question.

The proposed solution (which I haven't had time to verify yet) is to re-build the non-working assembly with signing turned off.

This assumes, of course, that you have the source code available. I had to build Ninject against .NET 4 myself (there was no released version for .NET 4 when I started the project), which is why I ended up in this situation in the first place.
