title: Visual Studio 2015 - Can't see code to existing project
body: <p>When I open a C++ project created recently on Visual Studio 2015 I am able to debug it and have it run, but the code window is blank. I've clicked all around and can not find anything to show me the code so I can continue to work on it.</p>
  <p>I have tried:</p>
  <ul>
  <li>F7: View Code does not work.</li>
  <li>Opening from the Solution Explorer window does not do anything.</li>
  <li>Searching Google, Stack Exchange, and YouTube tutorials for my identical problem.</li>
  </ul>
  <p>I suspect it is a very straightforward misunderstanding of the interface on my part, but wanted to get involved on Stack Exchange to figure it out.</p>
