설명

반환 된 Task 현재 작업이 완료 될 때까지 실행을 위해 예약 되지 것입니다.The returned Task will not be scheduled for execution until the current task has completed. 통해 연속 조건을 지정 하는 경우는 continuationOptions 매개 변수 충족 되지 않으면, 연속 작업을 취소할지 대신 예약 합니다.If the continuation criteria specified through the continuationOptions parameter are not met, the continuation task will be canceled instead of scheduled.
