Remarks

Instances of the Mutex, Semaphore, and EventWaitHandle classes can represent named system synchronization objects. When you use the Mutex.OpenExisting method, the Semaphore.OpenExisting method, or the EventWaitHandle.OpenExisting method to open a named system object that does not exist, a WaitHandleCannotBeOpenedException exception is thrown.
