How to restart one instance winforms application

Question

I have an application that I restart at 2 in the morning every morning using

Application.Restart();

the problem is that the inspection after a couple of weeks shows that about 6 copies are working.

I tried to limit the number of instances using

 bool IsOwned;
 Mutex m = new Mutex(true, Name, out IsOwned);
 if (!IsOwned)
         Environment.Exit(0);

But that did not work, because for some reason the recently stopped instance was still visible ... or at least this is my interpretation, and as a result the application did not restart.

Where am I wrong?

Answer 1

Make sure you click on the application exit event method that releases the mutex and closes it.
