New Post: Event for stop/Exit of started task

Is there an Event that gets raised when the process that I start via a Task gets stopped?

Currently I use

var processlist = Process.GetProcesses();

foreach(var theprocess in processlist)
 {
          if (theprocess.ProcessName != "DEMO")
                 continue;

          theprocess.WaitForExit();
          break;
 }

to enum all processes and If I find my started program I wait for Exit. Is there a better way?
