After much searching I couldn’t find a downloadable project that demonstrated how to use the MapItemsControl in the Silverlight Bing Maps Control. I thought this was a little strange. The CHM file that came with the SDK mentions the MapItemsControl as a way to enable data-binding on the map.
The Bing Maps Silverlight Interactive SDK is helpful but doesn’t allow you to download code.
I added a parser for KML (Google Maps Files) and demonstrate how to load that into a View Model that can be attached and bound to the Bing Maps Control.
Download the code here.
