title: ReSharper uninstall - Visual Studio no longer shows correct error highlighting
body: <p>I've been trying out ReSharper and decided that I'd like to uninstall it.  However, after doing so, Visual Studio no longer shows red underline highlighting that it normally uses to identify the location of errors in the code.</p>
  <p>This has happened on two of our PCs so far. I've tried a reinstall and a repair, but no luck. Any ideas how I can restore the highlighting in Visual Studio?</p>
