title: How to set a default Margin for all the controls on all my WPF windows?
body: <p>I want to set a default Margin of 3 on all the controls I put on all my windows and be able to override this value just on a really few number of items.</p>
  
  <p>I've seen some approaches like doing styles but then I need to style everything, I would prefer something than can be done for all the controls together. I've seen other things like the MarginSetter but looks like it does not traverse subpanels. I want the Margin only on the controls I put at the window, nothing to do with the borders or other things of the visual tree.</p>
  
  <p>Looks something pretty basic to me. Any ideas?</p>
  
  <p>Thanks in advance.</p>
