Description Roman 2016-11-10 15:39:22 UTC
I've created application which created Mutex:

_mutex = new Mutex(false, "SlideShow");

Than I've created another application which must get mutex from first application:

Mutex mut = Mutex.OpenExisting("SlideShow");

I start first application, then I start second application and then I catch Exception: 
"Named Mutex handle does not exist: SlideShow"

Why? I don't understand!

Mono doesn't support cross-process Mutex, Semaphore and Event.

It's great!!! Belissimo. But net. Framework supports it
