Mutex

public class System.Threading.Mutex : System.Any

A lock: one thread at a time between Lock and Unlock (not re-entrant: a thread that holds it must not lock it again). Run(() => …) holds it around a function. Dispose frees its handle (an undisposed one is freed when the object dies).

Takes it when no other thread holds it: whether it did.

method WaitOne() -> void
#

WaitOne and ReleaseMutex: the same as Lock and Unlock.

method ReleaseMutex() -> void
