I'm trying to set up unit testing with code coverage in VS2008, for a C++/CLI DLL which is compiled with /clr (not /clr:safe or /clr:pure - it has to be /clr because it uses MFC). The unit tests work perfectly but the coverage information only works if I compile with /clr:safe or /clr:pure. For /clr the Code Coverage Results window show...
