title: WPF equivalent of Form.BeginResize / Form.EndResize
body: <p>In WinForms we had the ability to hook <code>Form.ResizeBegin</code> and <code>Form.ResizeEnd</code> to be notified when a <code>Form</code> was about to begin resizing and after it had finished resizing.</p>
  
  <p>Is there a way to get similar functionality for a WinForms <code>UserControl</code> hosted in a <code>WindowsFormsHost</code> in WPF?</p>
