title: How to remove global FocusVisualStyle to all the Controls?
body: <p>I met the same problem as <a href="https://stackoverflow.com/questions/1055670/deactivate-focusvisualstyle-globally">Deactivate FocusVisualStyle globally</a>.</p>
  
  <p>But none of the answers can work.</p>
  
  <p>So, I just want to set all the Controls in my application <code>FocusVisualStyle="{x:Null}"</code>, any 
  effecive way to achieve this? </p>
  
  <p>I don't want to set each control separately.</p>
