title: Replacing desktop wallpaper / draw on the desktop
body: <p>I'd like to do some custom drawing to my windows desktop such that it appears to replace the desktop background (wallpaper). My first try was to get a DC for <code>desktopListView</code> and draw to it:</p>
  
  <pre><code>IntPtr desktopDC = GetWindowDC(desktopListView);
  Graphics g = Graphics.FromHwnd(desktopDC); //&lt;-- fails on out of memory error
  </code></pre>
  
  <p>I then tried to create a NativeWindow and capture the <code>WM_PAINT</code> message by assigning the native window's handle to the desktop and do my own drawing, but I was unable to see any messages to the desktop.</p>
  
  <p>Ideally I'd like to do this in WPF and not windows forms at all. Any clue how to create a WPF window that I can draw to that sits beneath the desktop icons but on top of the wallpaper such that it ignores any mouse messages and the desktop continues to work normally?</p>
