Does the .dispose() method do anything at all?

Question

I was experimenting with ways to get rid of some memory leaks within my application the other day when I realized that I know virtually nothing about cleaning up my resources.

Answer 1

Calling Dispose() will only release unmanaged resources, such as file handles, database connections, unmanaged memory, etc. It will not release garbage collected memory.

Garbage collected memory will only get released at the next collection. Usually when the application domain memory is deamed full.
