title: Visual Studio Test Explorer Can't find source
body: <p>I have a Dll which contains lots of tests, like 1200 of them.  The tests run fine and can be debugged. However I can't click on the test to go to the source this is supper annoying. </p>
  
  <p>I went about and did some due diligence on fixing the issue. The first thing I did was run symchk.  This is where it got really confusing.  The dll in question fails symchk if I just ran <code>symchk my.dll</code> however if i ran <code>symchk /s TheCurrentFolder</code> it said it passed. My understanding is that if the pdb is in the same folder it should be found automatically. </p>
  
  <p>I went and dumped the headers of the dll and found that the debug info was in the dll and pointed to the correct file. Lastly I added the pdb to the symbol cache ran symchk and it failed again stating that a file which does exist does not.  </p>
  
  <p>So the Question is has anyone ran into this before and is there something I can do about it.  Obviously visual studio is able to load the pdb but the test engine can't.  </p>
