What is an un/managed DLL? What is un/managed code? [duplicate]

Question

Could someone please explain to me what an un/managed DLL is? And what is un/managed code?

Answer 1

When you code with .net you get some memory management, garbage collection etc, so it is called managed code. Older versions are unmanaged (for the memory is managed by the programmer)

And to keep things easy, calling from managed code to unmanaged code can be a trye pain.

Answer 2

You will get a fair idea on managed and unmanaged code in following article -
