title: SystemJS modules with Visual Studio 2013 and TypeScript
body: <p>I'm trying to use SystemJS modules in Visual Studio 2013 with TypeScript, but Visual Studio shows errors. </p>
  
  <p>This is my <strong>setup</strong>:</p>
  
  <ul>
  <li>Installed TypeScript Tools for Microsoft Visual Studio 2013 1.8.5.0</li>
  <li>Uninstalled lower versions of TypeScript</li>
  <li><p>Project file (VS 2013 does not support tsconfig.json):</p>
  
  <p><code>&lt;TypeScriptToolsVersion&gt;1.8&lt;/TypeScriptToolsVersion&gt;
  &lt;TypeScriptModuleKind &gt;system&lt;/TypeScriptModuleKind&gt;
  &lt;TypeScriptTarget&gt;es5&lt;/TypeScriptTarget&gt;</code></p></li>
  </ul>
  
  <p>This is what I <strong>see</strong>:</p>
  
  <ul>
  <li>My project compiles successfully</li>
  <li>In the browser, AngularJs runs successfully</li>
  <li>But in Visual Studio, I see squiggly lines. Upon hovering it says 'expression statement is not assignment or call':</li>
  </ul>

  <p>This issue is related to <a href="https://stackoverflow.com/questions/34406087/visual-studio-2013-with-angular2-and-typescript">this question</a>, however, the answer there is 'use VS 2015', which simply is not an option for me.</p>
  
  <p>Is there any way to use SystemJS with TypeScript in Visual Studio 2013? It doesn't have to be ES6-style modules, just any combination of SystemJS and TypeScript will do. Thanks!</p>
