title: How to implement scrollviewer bouncing's animation in c# and wpf?
body: <p>I want to implement scrollviewer bouncing's animation in c# and wpf, like IOS's UIScrollview.</p>
  
  <p>When users scroll to top or end, it starts to decrease speed and bouncing.</p>
  
  <p>I think that google can search related issues, but i can not find.</p>
  
  <p>Does anyone have similar experiences?</p>
