does bing map control for WP7 provide a feature of "tracking shape manually"?

what I mean is something like this: http://help.arcgis.com/en/arcgismobile/10.0/apis/WindowsPhone/samples/start.htm

go to that ESRI sample and choose "Graphics" and then choose "Add interactively". In that sample, you can use mouse(if it's a phone, I suppose we can use fingers) to draw polygons, lines to the top of the map.

does the bi开发者_如何学编程ng map control for WP7 provide something similar?

Thanks

If the WP7 control is the same as the normal Silverlight control, you can add shapes to your Bing Map by adding MapPolygons(). If not, you can still add polygons and polylines (as well as other shapes) via Silverlight and display it on top.
