title: make visual studio editor not check ~ files
body: <p>I'm an Anaconda on Mac user and the newer versions of Anaconda are now downloading Microsoft's Visual Studio on the Mac. Pretty neat. Except that all of my files have been edited with EMACS and I have many <code>filename.py~</code> backup files, and VisualStudio is trying to check them all, and they don't check.</p>
  
  <p>How do I configure VisualStudio so that it doesn't try to check the backup files?</p>
