This class is typically used as a base class for synchronization objects. Classes derived from WaitHandle define a signaling mechanism to indicate taking or releasing access to a shared resource, but use the inherited WaitHandle methods to block while waiting for access to shared resources.

Use the static methods of this class to block a thread until one or more synchronization objects receive a signal.

System.Threading.WaitHandle implements the IDisposable.Dispose pattern. See Implementing Finalize and Dispose to Clean Up Unmanaged Resources. When you derive from System.Threading.WaitHandle, use the WaitHandle.SafeWaitHandle property to store your native handle operating system handle. You do not need to override the protected WaitHandle.Dispose(bool) method unless you use additional unmanaged resources.

All public static members of this type are safe for multithreaded operations. No instance members are guaranteed to be thread safe.
