Detecting when a weak object reference IsAlive status changes
I'm looking for a way to sneak a call back function whenever an object
reference has been garbage collected.
I know I can wrap the object in a weak reference, but I would still have
to poll a collection of references for status change.
I would prefer not to poll as that seems like a waste of CPU cycle when
nothing happens. Is there a more effective method to detect when an object
has been garbage collected?
Note: I do not have access to the object code and hence would not be able
to add the call back in the finalizer.
