I have a
at end of my testing program, I understand this is a blocking call and will free all un-reachable objects, if my program have no extra work any more, then the used memory should stayed in a fixed value, and this has been proved via the Graph and statistics
But at this point, once I performed a SnapShot
, I still can see a extra memory(Live managed bytes) drop down , what did the snap shot
do here? not just trigger a Full GC?

When you collect a snapshot in the profiler, the profiler performs a sequence similar to:
It may even repeat this if it believes that there are still more instances to finalize.
So in your case, there's a possibility that there are instances with pending finalizers after your call to GC.Collect() and that would explain why the live bytes value decreases when you collect the snapshot.
