Using Visual Studio 2012, into the immediate window, I typed:
.load SOS
Then, I investigated my class with this command (still in the immediate window).
!DumpHeap -type
I could see how many objects there were of this type in the heap. I could see their addresses in memory.
!gcroot
This command showed me where they came from and what other objects had references to them.
Finally:
!finalizequeue -allready
This allowed me to verify that although the object wasn't finalized yet, it was due to be whenever the Garbage Collector got around to it and therefore, my program wasn't leaking.
