We implemented a custom TiledProvider to access a private OSM tile server with your 2011 Q2 release - we used your example code
The only addition is that we set the GeoBounds on our provider before we pass it to the RadMap instance.
VDM_OSM_Provider provider =
.bgMap.Provider = provider;
When we load this silverlight application into a Browser (IE or Firefox) the memory consumption of the plugin container process increases with every zoom step. When reaching zoom level 14 we reach 1.7GB and the CPU usage goes up to nearly 100%. We also observe many more calls to TiledMapSource.GetTile() then would actually be necessary.
We tracked it down to the GeoBounds of the provider: when not setting the GeoBounds, everything performs normal.
Is this a bug or are we doing something wrong?
Thanks in advance,
