title: Typescript 1.4: Wrong syntax highlighting in Visual Studio
body: <p>Typescript 1.4 has been released recently, providing new possibilities like unions.</p>
  
  <p>I installed the new version for Visual Studio, however the syntax highlighting doesn't recognise unions:</p>
  
  <pre><code>var member: string|number;
  </code></pre>
  
  <p>Although it can be compiled without problems, the syntax checker hovers the definition and any usage of the variable <code>member</code>.</p>
  
  <p>What do I need to update to get this working?</p>
