title: create-react-app + Visual Studio + F5 = "Unexpected token import"
body: <p>React newbie here. How can I enable Visual Studio 2017 to run (via F5) a react.js app that's been created by <a href="https://github.com/facebookincubator/create-react-app" rel="nofollow noreferrer">create-react-app</a>?  Here's the steps I've followed so far:</p>
  
  <ul>
  <li><code>npm install -g create-react-app</code></li>
  <li><code>create-react-app my-app</code></li>
  <li>In Visual Studio 2016 RC (5.0.26206.0 D15REL) with Node.js Tools( 1.3.41102.00) I created a node.js project using the "from existing code" option. </li>
  <li>I set the startup file to src/index.js</li>
  <li>F5</li>
  </ul>
  
  <p>I get this error: </p>

  <p><code>npm start</code> works fine. I assume that I need to instruct Visual Studio to either execute <code>npm start</code> or to duplicate what <code>npm start</code> is doing. I'm sure I'm not the first person that's tried this. What's the recommended solution?</p>
