Black day

1. test I wrote aren't visible in test explorer filtered by owner at VS2012. - Forgot to add [TestClass] attribute
2. http://ambilykk.com/2010/04/21/wpf-the-tag-xxx-does-not-exist-in-xml-namespace-clr-namespaceyyy/ - deleted file, created then. -  succeeded to see its instantiation in XAML succeeded
3. Couldn't get test into debugger. Reason : cleanup routine was private. It was discovered and test even wasn't tried to run.

        [TestCleanup]
        public void CleanupTestContext()
        {
            TestRunningContext.Cleanup();
        }
