C# how to implement a termination handler

Question

I want to serialise an object in C# if a user stops a console application.
I have seen various questions dealing with this, but no final answer.
I will need to catch Ctrl+c, clicking the top right corner and stop process from the task manager.
Is it safe if I have an implementation object and add this as a finalizer to it?

Answer 1

Just handle AppDomain.ProcessExit.
