I've been looking for an open source mapping / GIS framework along the lines of OpenLayers but written in Silverlight. Unfortunately I have not been able to find one.
Preferably it would be able to consume services (e.g., maps, tiles, geocoding services) from the major map / GIS providers, including (in order of preference):
Are there any open source GIS frameworks written in Silverlight with similar functionality to OpenLayers or the ArcGIS Server Flex ADF?
