title: Test Explorer Not Showing List of Unit Tests with Network Drive
body: <p>I had a simple C# program that had a set of Unit Tests.  This was developed on Visual Studio 2010.  Now on another computer I tried to reload this solution with Visual Studio 2012 and run the tests.  I was able to rebuild the solution successfully however none of the unit tests show up in Test Explorer.  The Visual Studio project (solution) was located on a LaCie Ethernet network drive.  I copied the entire solution to my local C: drive, closed the solution from the network drive and reopened the copied one on local C: drive.  Now when I build solution Test Explorer shows all tests.  I went back and opened the copy on the network drive and again Test Explorer shows no tests. It says to build the solution to see a list of tests, but after successfully building the solution which includes the main project and the unit test project it still displays the same message. See image below:

  <p>Why is it having project located on network drive causes Unit Testing to fail like this with no failure message at all?</p>
