This method cancels a running configuration task. Multiple cancel requests are treated as a single cancellation request. Cancelling a completed or an already cancelled task throws

ServiceIdle

exception. If successfully canceled, the

StateInfo.error

property is set to

RequestCanceled

. A cancel operation is asynchronous. The operation may return before the task is cancelled. After invoking it, the configuration task continues to remain working, and it can still succeed. In such a situation, the

StateInfo.cancelled

property is set.
