Answer
IDisposable defines a contract for releasing unmanaged resources such as file handles, sockets, and database connections.
Implement IDisposable when your class owns unmanaged resources that the garbage collector cannot free automatically.
Quick Answer
IDisposable has one method: Dispose(). Implement it when your class holds unmanaged resources (file handles, DB connections, sockets) or subscribes to events. Wrap in using or call explicitly. The GC will never call Dispose automatically — that is your responsibility.
