As I understand it, after I set all the roots of an Ref-Type object to null, the Ref-Type object is logically deleted from the stack, but remains in existence on the manged-heap. If the Ref-Type object uses some native resources, such as an opened-file, do I have to ...

My web application needs to call a .NET assembly which seems to me that allocates "a lot" of memory for a web application (perhaps I'm wrong, that's why I'm asking).
