c# - Session containing items implementing IDisposable

Question

In ASP.NET if items are left in the session state that Implement IDisposable but are never specifically removed and disposed by the application when the session expires will Dispose be called on the objects that any code in Dipose() will execute?

Answer 1

I'd disagree with Sean's answer; firstly, finalizers should not be routinely added to classes, even if they are IDisposable - finalizers should only really be used in classes that represent unmanaged resources. Conversely, a class with a finalizer often is also IDisposable.

Re the question: is Dispose() called - no, it isn't. The object will be garbage collected at some point in the future (indeterminate), but that is about it. A finalizer wouldn't add much here, as any encapsulated objects will also already be eligible for collection (assuming that they aren't referenced elsewhere).
