title: Scope of WPF resource : Is pushing it to application scope (app.xaml) good for performance?
body: <p>A) If I have a resource to be used from a user control, which one is more good performance wise..?<br>
  To include it in the user control scope itself  or refer the resource from app.xaml..?</p>
  
  <p>B) Now we have all the 100s of styles referred from appl.xaml.
  Will moving them to their respective user controls be worth the effort..?</p>
