ArcGIS Silverlight and Bing Maps

[aadd]

Hi,

I looked at the ArcGis Silverlight resources and read and tested some concepts from there.
I also found this concept: Using Bing Maps where you can use Bing Maps with the esri client.
That sounded interested so i followed the tutorial and made my silverlight application using esri and bing maps. After i done that I looked for more tutorials related with esri and bing maps but couldn't find any.

Now I have the following questions:

Is there any documentation about how I can use esri with bing maps.

And also why is it useful to use ArcGIS with Bing Maps, doesn't Bing Maps have their own Silverlight control?

Here is a link to the SDK. We support using bing map layers all you need is your bing token. We also support OpenStreetMaps as well which you can find in the ToolkitDatasources section.
