title: Angular2 @types references
body: <p>I'm working on and Angular2 project using webpack. I'm having issues with Jasmine references and definitions, where Visual Studio Code complains about any Jasmine syntax (describe, it, beforeall and the rest of the lot). The same applies to the browser object.</p>
  
  <p>I found <a href="https://stackoverflow.com/questions/39020022/angular-2-unit-tests-cannot-find-name-describe">another post</a> mentioning the necessity of references, eg:</p>
  
  <pre><code>///&lt;reference path="./../node_modules/@types/jasmine/index.d.ts"/&gt;
  </code></pre>
  
  <p>this works perfectly fine if inserted at the very top of the specs, however, where and how should these references be placed to be available globally? I tried in the app.module.ts, but intellisense still complains.</p>
