title: Implement Window Drag and Drop WPF
body: <p>I had to create a new Window from scratch using MahApps.Metro like <a href="http://mahapps.com/MahApps.Metro/#roll_your_own_window" rel="nofollow">this</a>. This creates for you a borderlesss Window without the standard Window buttons (Close, Restore or Minimze).</p>
  
  <p>I implemented these buttons and it works pretty well. The thing that I see that is not like all anothers windows is the behavior that allows the user to change the position of the window, using drag and drop.</p>
  
  <p>I was looking for but I couldn't figure how to do it.</p>
  
  <p>How should I implement the behavior of drag and drop in a non-standard window?</p>
