title: WPF quick notification control
body: <p>Developing a WPF application using MVVM, I have hit a point where I've got a "save" button on an editable datagrid which does behind the scenes processing but doesn't actually update anything in the UI, so the user has no way of knowing that the save has been successful.</p>
  
  <p>I'm pretty new to WPF, and I presumed there would be a simple flash message control that one could use to notify the user of success and then faded away without them having to do anything. But it seems there's nothing in vanilla WPF that can do this, and there don't seem to be a lot of custom solutions either.</p>
  
  <p>I don't want to use any kind of messagebox because it forces the user to take an action to dismiss the alert - I need something that breifly flashes a message without interfering with their workflow. I'm after something a bit like the JavaScript Toastr library -</p>

  <p>can anyone either point me at an existing control for this, or where I might start at building one?</p>
