title: Does WPF have a Timer control?
body: <p>I can't seem to find it in the Toolbox.</p>
  
  <p>I've did a Google search, and found:
  <a href="http://www.c-sharpcorner.com/UploadFile/mahesh/WPfTimer09292009090518AM/WPfTimer.aspx" rel="nofollow noreferrer">http://www.c-sharpcorner.com/UploadFile/mahesh/WPfTimer09292009090518AM/WPfTimer.aspx</a></p>
  
  <p>However, I can't seem to add a reference to <code>System.Windows.Threading</code> because it isn't displayed as an available library.</p>
  
  <p>I've even made sure to use the full .NET4 framework, and not the client framework.</p>

  <p>Any suggestion on what to try next?</p>
  
  <p>Thank you.</p>
