title: "'WinJS' is not defined." and "Windows' is not defined."
body: <p>Sorry about my English. 
  I started learning to develope a Windows Store App. And i found a tutorial <a href="http://blogs.msdn.com/b/davrous/archive/2012/05/11/windows-8-html5-metro-style-app-how-to-create-a-small-rss-reader-in-30min-part-1-2.aspx" rel="nofollow">here</a>. I follow it, create a new Javascript Windows Store App. But when i build my app, with no code added, JSHint show my error like that:</p>
  
  <pre><code>'WinJS' is not defined.
  'Windows' is not defined
  </code></pre>
  
  <p>There is my default.html</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
