I have 5 test projects in my solution. If I run the Visual Studio test tools (Test | Run | All Tests in Solution) it runs the tests in all 5 projects. If I run the ReSharper test tools (ReSharper | Unit Tests | Run All Tests from Solution) it only runs the tests in 4 of the projects. It doesn't show the 5th project in its list or run the test in it. Where should I start troubleshooting this? Thanks.
