dotCover cannot load test Follow

Hello,

I am still trying (and hoping) to get dotCover to work, and with the latest releases (Resharper 6.1 and dotCover 1.2) I had hopes that
my issues (not test are run) where resolve. But I am afraid I still get errors, but this time it atleast says so, and not silently does nothing.

The message I get in an error:

[Window Title]
ReSharper Test Runner

[Main Instruction]
Unit Test Runner failed to load test assembly


[Content]
System.MissingMethodException: Method not found: 'Void System.Runtime.Versioning.TargetFrameworkAttribute.JetBrains_Profiler_Core_Instrumentation_Begin(UIntPtr ByRef)'.

I am using latest resharper 6.1, dotCover 1.2, VS 2010 on a WinForms solution targeting .Net 4 Client Profile, the test projects are .Net 4 full as some of the testing frameworks requires this.
