title: How to use "compileOnSave" in VS Code?
body: <p>Typescript has a configuration option for auto compilation of typescript, <a href="http://www.typescriptlang.org/docs/handbook/tsconfig.json.html" rel="nofollow">as documented here</a>.</p>
  
  <pre><code>{
     "compileOnSave": true,
     "compilerOptions": {
         "noImplicitAny" : true
     }
  }
  </code></pre>
  
  <p>But simply including this in my tsconfig.json file is not enough to trigger auto compilation. I use MS Visual Studio Code as my IDE.
  How do I trigger the "compile on save" behavior?</p>
