What is the difference between managed and unmanaged resources?

Quick Answer Managed resources are controlled by the CLR â€” objects, arrays, strings â€” the GC cleans them up automatically. Unmanaged resources are outside the CLR â€” file handles, sockets, DB connections â€” you must release these manually using IDisposable. Forgetting to do so causes resource leaks.

Answer

Managed resources are controlled by the CLR (objects, arrays, strings), while unmanaged resources (file handles, sockets, DB connections) must be released manually via IDisposable.

Failure to release unmanaged resources leads to leaks and OS-level exhaustion.
