C#: Non-Winforms way to exit the application?

Question

I know about Application.Exit() but what if I'm not in a windows forms application but in a simple class library, how do I signal for the application to exit?

Answer 1

Environment.Exit() -- but why would you ever want to do this from a method in a class library?

Answer 2

P/Invoke ExitProcess, perhaps. Or if you're really in a hurry, TerminateProcess.
