title: Typescript - "SourceMap file read failed" when running solution in VS2013
body: <p>I encounter some weird issue when launching my TypeScript solutions (it happens even with the default solution which comes along with a new TypeScript project in visual-studio). Sometimes (it happens very often), when i launch my TypeScript solution (with IE), it takes quite a while to load (i just get a blank white page for a while (for around 10-15 seconds), and after that the homepage is loaded). In the output window of VS2013, i can see that the reason for that is because there was a timeout in reading few of the source-map files (image is attached).</p>

  <p>Does anyone knows why it happens? Ever happened to anyone? it is very annoying... :(
  Any help will be much appreciated.</p>
  
  <p><strong>I'm using Win8 / VS2013 / TS 0.9.5 / IIS Express.</strong></p>
