title: Navigate To (CTRL + comma) in Visual Studio does not work
body: <p>The &quot;Navigate To&quot; function (CTRL + comma) does not work on my solution. It gets stuck on &quot;Found 0 matching results&quot; while the little progress bar stays there but is empty.</p>
  <p>I searched for some kind of IntelliSense cache file next to the .sln, but all I found was a .suo file which I deleted but it did not help.</p>
  <p>Why is it not working?</p>
