I am using WinDbg with SOS . Attach to the process and use the following commands:
!dumpheap -stat display all objects in the managed heap.
!clrstack -a display a stack of managed calls, including parameters and locales for the current thread. Keep in mind that release versions may limit the number of local users available.
~Xs switch to stream X.
SOS has many other useful commands for checking managed applications.
