If you want the app to exit when the main thread has finished, you can just make the new thread a background thread:

Thread t = new Thread(Main.MyThread);
t.IsBackground = true;
t.Start();

Basically the process will exit when all the foreground threads have exited.

Note that this could be bad news if the background thread is writing a file when the form is closed, or something similar...
