title: Full screen on many screen (WPF)
body: <p>I'm using WPF</p>
  
  <p>I would like that my windows take the entire screen of all the screen.</p>
  
  <p>If I use the code snippet :</p>
  
  <pre><code>WindowState = WindowState.Normal;  
  WindowStyle = WindowStyle.None;  
  Topmost = true;  
  WindowState = WindowState.Maximized;
  </code></pre>
  
  <p>it takes only the active screen.
  How to fill all the screen ?</p>
