title: How to use image in IRandomAccessStreamReference for Shape.Fill
body: <p>I have an image stored as IRandomAccessStreamReference which I need to use as the fill in an Ellipse.  How would I go about using this?</p>
  
  <pre><code>...
   static IRandomAccessStreamReference myThumbnail;
  ...
   var contactStore = await ContactManager.RequestStoreAsync();
   var contact = await contactStore.GetMeContactAsync();
   myThumbnail = contact.Thumbnail;
  ...
   Ellipse ellipse = new Ellipse
              {
  
                  Height = 32,
                  Width = 32,
                  Fill = myThumbnail, // How do I use this?
               };
  </code></pre>
