title: Duplicate Identifier in WinJs.d.ts
body: <p>I am trying to use TypeScript  in a Windows 8 app (html5/JS)</p>
  
  <p>I have looked at the <a href="http://typescript.codeplex.com/SourceControl/changeset/view/deb84dba2fde" rel="nofollow">sample app</a> </p>
  
  <p>The app uses a typing definition file for WinJS (WinJS.d.ts). </p>
  
  <p>I need to edit this file as it is not complete. However the file has an interface extension for the Type Element adding a property for winControl(typed to any).</p>
  
  <p>This line gets and error of "Duplicate identifier 'winControl'" I am unable to locate and other place this is. </p>
  
  <p>Also, there are locations in my code that i get errors as there is no property named winControl    </p>
