Instance has been disposed! However still Referenced By...

We have an application that shows that a previous instance has been disposed, however it is still referenced by something. What does this mean?

If the instance is still included in a snapshot, then it has not been garbage collected by the runtime. Since it has not been garbage collected, it must somehow be referenced by a root, and hence it is referenced by at least one other instance or root (which you will see in the "Referenced by" list).

The fact that the instance has been disposed usually indicates that the instance should no longer be used and that it should be elibible for garbage collection. It is, however, possible that you have disposed instances that should not be GCed, e.g. instances that are returned to a pool after being disposed.
