Running with opencover

[ilengyel]

We get the following exception when we run our xunit tests wrapped in an open cover:

    CustomControls.TreeListView.TreeListViewTests.BringIntoObject [FAIL]
      System.NotSupportedException : Specified method is not supported.
      Stack Trace:
           at Pose.IL.MethodRewriter.Rewrite()
           at stub_System.CannotUnloadAppDomainException_VisitedCritical(Int32 , RuntimeMethodHandle , RuntimeTypeHandle )
           at dynamic_System.CannotUnloadAppDomainException_SafeVisited(Int32 )

           at dynamic_CustomControls.TreeListView.TreeListViewTests+<>c__DisplayClass0_0_<BringIntoObject>b__0(<>c__DisplayClass0_0 )

If we run the same set of tests without open cover, the desired methods appear to be shimmed just fine. I attempted to reproduce this in a minimal project to no success yet, and it also shims just fine with open cover enabled. Let me know if more effort is needed to attempt to reproduce.

@ilengyel I'm working on reproducing this

Same when using dotCover. I guess having both doing IL emit on top of each other isn't working properly?
