title: How to cast a List<T> to an ObservableCollection<T> in wpf?
body: <p>I am in wpf, and have a generic list: List.
  Now I wish to cast it to a generic observable collections: ObservableCollection.</p>
  
  <p>I understand I can iterate over the list and add each individual item to the Observable collection.
  However, it seems to me there has to be a built-in way of doing this. </p>
