Magnifying Glass with a Bing TileLayer

Question

Has anyone gotten to work the Magnifying Glass with an ESRI.ArcGIS.Client.Bing.TileLayer?

My base map is a ESRI.ArcGIS.Client.Bing.TileLayer and I would like to use the Magnifying Glass on it.  The Magnifying Glass is blank (dark) and displays nothing.  If I use an "ArcGISTiledMapServiceLayer" it works fine with the URL property set.

Since I use an ESRI.ArcGIS.Client.Bing.TileLayer I do not have a URL property, but a Bing Map key and TileLayer properties.

I have tried to cast the ESRI.ArcGIS.Client.Bing.TileLayer into an ArcGISTiledMapServiceLayer, but  the Magnifying Glass remains blank.

Casting code:if (MagnifyingGlass != null) MagnifyingGlass.Layer = MyMap.Layers[0] as ArcGISTiledMapServiceLayer;

Any ideas?

Thanks Jennifer!
It works great now.  Your code-behind (C#) sample made it possible.
  
I add the Bing.TileLayer at run-time, rather than using XAML to prevent Visual Studio 2010 crashes during design.  (Visual Studio 2010 crashes if the Bing Maps token is placed in XAML; hence, I load the TileLayer at run-time.)

Have you looked at this SDK sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#MagnifyingGlass MagnifyingGlass need a different instance of TiledMapServiceLayer. Layers already associated to another map will throw an exception. or in code-behind: MyMagnifyingGlass.Layer = new ESRI.ArcGIS.Client.Bing.TileLayer() { ID = "BingLayer", LayerStyle = ESRI.ArcGIS.Client.Bing.TileLayer.LayerType.AerialWithLabels, ServerType = ESRI.ArcGIS.Client.Bing.ServerType.Production, Token = this.LayoutRoot.Resources["BingToken"] as string };
