title: Check if app is already running, and if kill it C#
body: <p>I know that <code>Mutex</code> can be used to determine if another instance of application is running, but can I find from <code>Mutex</code> the PID or name of the other instance? And if not from <code>Mutex</code>, is there another way around to kill other instance if it is running. This is kinda tricky, because it also must be bounded to user and it shouldn't use files to do the trick (I know that <code>Mutex</code> creates files, but those created by .NET via internal functions are OK).</p>
  
  <p><strong>Note that I need to get info of other instance to kill it.</strong></p>
  
  <p>Thanks for reading!</p>
