title: How to re-size window in WPF when Allow Transparent is True
body: <p>As you known, when allow transparent property is true, the border of window is hidden and we cannot re-size the window. We only re-size the window if we set ResizeMode is CanResizeWithGrip, but the solution is not good because we can re-size window when it's maximized and change by right corner of the window instead of all of 4 corners, so the question is how to how to re-size window in WPF when Allow Transparent is True without using CanResizeWithGrip?</p>
  
  <p>Thanks in advance!</p>
