Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsAutoResetWhen signaled, the EventWaitHandle resets automatically after releasing a single thread. If no threads are waiting, the EventWaitHandle remains signaled until a thread blocks, and resets after releasing the thread.
Supported by the XNA FrameworkSupported by Portable Class LibrarySupported in .NET for Windows Store appsManualResetWhen signaled, the EventWaitHandle releases all waiting threads and remains signaled until it is manually reset.

The following code example uses the SignalAndWait(WaitHandle, WaitHandle) method overload to allow the main thread to signal a blocked thread and then wait until the thread finishes a task.

The example starts five threads and allows them to block on an EventWaitHandle created with the EventResetMode.AutoReset flag, then releases one thread each time the user presses the ENTER key. The example then queues another five threads and releases them all using an EventWaitHandle created with the EventResetMode.ManualReset flag.

No code example is currently available or this language may not be supported.
