title: how to show / hide WPF window by blur effect
body: <p>I have a WPF window. I want to add blurring effect. I.e. When i say <code>Show()</code> or <code>Close()</code> it should blur into view and blur out of view.</p>
  
  <p>I tried using <code>Effect = new BlurEffect()</code>, but i believe it is when windows is visible</p>
  
  <p>Edit:
  I figured out that I could actually control the <strong>opacity</strong>, so I have decided to fade the window.</p>
