This is a multipart question. Using the Bing Map Api with Silverlight and REST is it possible to send a query for multiple layers that would return a grid of layers that you could select features from a layer. And also what would be the data volume constraint on such a query? Or rather what are the limitations on such a query? Thanks for any help.

Ok, your question isn't very clear. You can use the Bing Maps REST services with the Silverlight control. Here is a code example: http://rbrundritt.wordpress.com/2012/01/06/bing-maps-rest-service-net-libraries/
As for the multiple layers. You can have as many layers of data as you want using MapLayers to seperate them. You can add Pushpins, Polyline, and Polygons to these layers and make them interactive. Note that the REST services do geocoding, routing, traffic incident and static imagery. If you want POI data you will have to use the Bing Spatial Data Services.
In terms of limitations it really all depends on the type of query and the service you are using. It is possible to get 95MB worth of data on the Silverlight map control without any performance issues.

Thanks Richard. Completely new at using the Bing Map API and I'm asking the questions on behalf of someone else who is my manager and I have no idea what to really ask. But what you gave me goes a long way.
Tuesday, June 26, 2012 5:16 PMI have another question Richard. Is it possible to query several layers like polylines and polygons in the same REST query, return a grid of the layers queried and have then click on an entry in the grid to select that feature? The question may not make sense but that is what we are aiming for.
