title: How to programmatically create a WPF window in a WinForm application
body: <p>I have an existing WinForm app which is too much to port to WPF right now.
  However, I need a window with some tricky transparency behavior that I cannot achieve in a WinForm (yes, tried Layerd Windows but it's a no-go).</p>
  
  <p>WPF allows the transparency behavior I need beautifully and simply.</p>
  
  <p>I googled of course, but can only find hints how to create a WPF control within a WinForm but that is NOT what I need. I need a separate WPF window that is completely independant of my other Forms.</p>
  
  <p>The WPF window will be a rather simple full-screen and borderless overlay window where I will do some simple drawings, each with different transparencies.</p>
  
  <p>How can I create a WPF window within a WinForm application?</p>
