title: What purpose does the Silverlight.js file serve?
body: <p>I asked <a href="https://stackoverflow.com/questions/5805563/silverlight-js-file-broken-in-ie9">this question</a> this morning.  Essentially there's an IE hack in the Silverlight.js file that breaks in...IE9.</p>
  
  <p>The response I got was to get rid of the file altogether which, to my surprise, seemed to work after preliminary testing.</p>
  
  <p>So does this file actually serve a purpose?   </p>
