title: Created basic JSX file to test ReactJS is not working
body: <p><a href="https://i.stack.imgur.com/xYeYP.png" rel="nofollow noreferrer">here is a pic of the error</a>I created a basic MVC Project and added React.js to it. I have created the following basic component. when executing the app, I get a 500 error. </p>
  
  <pre class="lang-js prettyprint-override"><code>class Admin extends React.Component {
      constructor() {
        super();
      }
  
      render() {
        return (
          &lt;div&gt;
            test
          &lt;/div&gt;
        );
      }
  }
  
  ReactDOM.render(
      &lt;Admin /&gt;,
      document.getElementById('admin')
  );
  </code></pre>
  
  <p>I have added the following packages</p>
  
  <pre><code>React.js
  React.Core
  React.Web
  ReactWeb.MVC4
  System.Web.Optimization.React
  </code></pre>
  
  <p>Not sure why it is failing on such a basic jsx file. Any Idea what I am missing?</p>
