title: WPF frozen BitmapImage not showing
body: <p>I am using a viewmodel bound to an image property on the UI and the viewmodel contains an ImageSource property. I set that property using the following function</p>
  
  <pre><code>    private BitmapImage GetImageFromUri(Uri urisource)
      {
          if (urisource == null)
              return null;
  
          var image = new BitmapImage();
          image.BeginInit();
          image.UriSource = urisource;
          image.EndInit();
          image.Freeze(); //commenting this shows the image if the routine is called from the proper thread.
  
          return image;
     }
  </code></pre>
  
  <p>For some odd reason, in the following code, when I call Freeze on my BitmapImage, it does not appear on the main window.I get no exception or crash. Can anybody help me with this?
  I am setting the image property asynchronously so I need to be able to use the created image, assuming the GetImageFromUri call was made from a thread other than the UI thread.</p>
