title: Win7 progress bar on the application icon in the task bar?
body: <p>I was wondering how you can turn the application icon in the task bar on windows 7 into a progress bar. I noticed some other applications doing this such as IE9, when you download the icon shows the download progress in the task bar.</p>
  
  <p>Can someone tell me how to do this in a .Net 4.0 WPF application?</p>
