Find references to the object in runtime

Question

I have an object, which lives forever. I am deleteing all references I can see, to it after using it, but it still not collected. Its life cycle is pretty sophisticated so I

Answer 1

The garbage collection in .NET is not a counting scheme (such as COM), but a mark-and-sweep implementation. Basically, the GC runs at "random" times when it feels the need to do so, and the collection of the objects is therefore not deterministic.

You can, however, manually trigger a collection (GC.Collect()), but you may have to wait for finalizers to run then (GC.WaitForPendingFinalizers()). Doing this in a production app, however, is discouraged, because it may affect the efficiency of the memory management (GC runs too often, or waits for finalizers to run). If the object still exists, it actually still has some live reference somewhere.
