System.Activities.Statements.CancellationScope

Associates a main path of execution with a cancellation handler. The Cancellation Scope has two sections where you can include the child activities: the Body and the CancellationHandler. Activities included in the Body section can only be canceled if they have not been completed.

If a cancellation request is scheduled and the activities in the Body have not completed, then the Cancellation Scope will be marked as Canceled and the CancellationHandleractivities will be executed.
