title: WPF ICollectionView Refresh
body: <p>Is there any way how to do </p>
  
  <pre><code>ICollectionView.Refresh() 
  </code></pre>
  
  <p>or </p>
  
  <pre><code>CollectionViewSource.GetDefaultView(args.NewValue).Refresh();
  </code></pre>
  
  <p>in a <strong>separate thread</strong>? </p>
  
  <p>I know I can use dispatcher, but this collection is binded to a ListView and it throws cross thread Exceptions.</p>
  
  <p>The reason why I need a second thread is, that I have Control which displays a list of IMyItems. When filtering this Collection (by user text change input), I want to be able to display my animation that CollectionView is changing.</p>
