title: Visual Studio 2010 does not discover new unit tests
body: <p>I am writing some unit tests in Visual Studio 2010. I can run all tests by using "Run all Tests in Current Context".</p>
  
  <p>However, if I write a new unit test, it does not get picked up by the environment - in other words, I am not able to find it in Test List Editor, by running all tests, or anywhere else. If I unload the project and then reload it; the new test is available to run. </p>
  
  <p>When I am adding a unit test, I simply add a new method to an already existing TestClass and decorating it with  [TestMethod] attribute - nothing fancy.</p>
  
  <p>What might be causing this behaviour, and how do I make it work ? </p>
