title: Typescript in VS2012: (automatically) generating .js from .ts
body: <p>I've added <code>file1.ts</code> and I can see there's a dependent to it - namely <code>file1.js</code>.</p>
  
  <p>I notice that any changes I made to <code>file1.ts</code> - <code>file1.js</code> doesn't get automatically re-generated.</p>
  
  <p>The only workaround I have at the moment is by calling <code>tsc.exe</code> - as part of pre-build event.</p>
  
  <p>My question is - are there any better workaround or maybe a setting somewhere I might've missed ?</p>
