More Information

The RPM and the GC Heap Viewer feature provide real-time counter data (ranging from Garbage Collector activity to type loading information) on a running NETCF application. The GC Heap Viewer lets you capture the managed heap at any moment during which your application is running to view live references and lets you compare multiple snapshots to find memory-leak issues.
