title: JavaScript IntelliSense for external library is not working in Visual Studio 2015 Update 3
body: <p>I am trying to use the Azure Document DB Server-Side JavaScript IntelliSense in Visual Studio 2015 Update 3.</p>
  
  <p>I have downloaded the <code>.js</code> file from Document DB's <a href="https://github.com/Azure/azure-documentdb-js-server/tree/master/utils" rel="nofollow noreferrer">GitHub site</a> into my Visual Studio JavaScript references folder:</p>

  <p>And referenced it in my <code>.js</code> file, but I don't see any Document DB IntelliSense:</p>

  <p>However, if I open <code>DocDbWrapperScript.js</code> in VS the IntelliSense starts working:</p>

  <p>Have I missed some config somewhere to make the <code>/// &lt;reference path="foo.js" /&gt;</code> syntax work?</p>
