It appears that having an ArcGISTiledMapServiceLayer inside a GroupLayer, causes a memory leak. As the user pans/zooms around the application, the memory footprint continually grows.
Using the simplest example, a map with one group layer containing the ESRI tiled street map, the memory footprint of the application grows to over 100MB after a minute or so of moving around the map.
This issues appears in both Silverlight and WPF. Any help resolving is much appreciated.
