Question

I have an application that I restart at 2 am every morning using

Application.Restart();

the problem is that a inspection a couple of weeks later shows that there are 6 or so instances running.

I tried to limit the number of instances by using

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

But this didn’t work as for some reason the recently stopped instance was still visible…or at least that’s my interpretation and as a result the application didn’t reatart.

Where have I gone wrong?

Answer 1

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