title: How do I include a timer in a universal windows app with c#
body: <p>I need a timer in my universal windows app. I have read that the only one available for universal windows apps is <code>System.Windows.Threading.DispatcherTimer</code>. In order to use this I manually added the <code>WindowsBase.dll</code> to my app's references in the solution explorer in visual studio. Now I get the following error:</p>
  
  <pre><code>Error   3   Cannot find type System.ComponentModel.TypeConverter in module System.dll.  Game.Windows
  </code></pre>
  
  <p>The error goes away if I delete the <code>WindowsBase</code> reference. What am I doing wrong?</p>
