Communicates a request for cancellation.
Assembly: mscorlib (in mscorlib.dll)
Any callbacks or cancelable operations registered with the CancellationToken will be executed.
Cancelable operations and callbacks registered with the token should not throw exceptions.
However, this overload of Cancel will aggregate any exceptions thrown into an AggregateException, such that one callback throwing an exception will not prevent other registered callbacks from being executed.
The ExecutionContext that was captured when each callback was registered will be reestablished when the callback is invoked.
