title: Visual studio 2015 solution explorer doesn't refresh files?
body: <p>My Visual studio 2015 solution explorer doesn't refresh when I change files on disk and there is (as far as I can see) no refresh button anymore.</p>
  
  <p>In explorer everything looks as it should and after performing my "refresh"-methods below all files shows again.</p>
  
  <p>My solutions so far:</p>
  
  <ol>
  <li>Unload and reload project</li>
  <li>Refresh Visual Studio</li>
  </ol>
  
  <p>This is especially annoying when running builds with gulp which is adding, changing and removing files.</p>
  
  <p>Am I missing something obvious?</p>
  
  <p>Ps. It does not have to do with option "Show All Files". The doesn't show as "transparen" not-included-files either.</p>
