Performing pre-termination activities using ProcessExit event

In many cases we use resources such as files, storage, connections etc. in our application. Being a programmer it is our responsibility to free up all the used resources before terminating our program. We have try {} finally{} which does the same thing. This can be achieved by AppDomains ProcessExit event.

    class Myclass
        // will print 1st also sets up Event Handler
        static Myclass()
            Console.WriteLine("I am inside Myclass");

        static void Main(string[] args)
            Console.WriteLine("I am inside Main()"); // it will print 2nd
            AppDomain.CurrentDomain.ProcessExit += new EventHandler(CurrentDomain_ProcessExit);

        static void CurrentDomain_ProcessExit(object sender, EventArgs e)
            Console.WriteLine("I am the last one to run");

Executing this program will print
I am inside Myclass
I am inside Main()

Obviously the last statement will not be visible, as the application is still running. But, you can try writting in an event log to see how it works.
