public void Cancel(

)

abstract Cancel :

override Cancel : 
        throwOnFirstException : bool -> unit 

The associated cancelable will be notified of the cancellation and will transition to a state where IsCancellationRequested returns true. Any callbacks or cancelable operations registered with the cancelable will be executed. Cancelable operations and callbacks registered with the token should not throw exceptions. If throwOnFirstException is true, an exception will immediately propagate out of the call to Cancel, preventing the remaining callbacks and cancelable operations from being processed. If throwOnFirstException is false, this overload 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.
