CompensableActivity allows a developer to specify a Body activity that defines a long-running task that performs their core business logic. It also allows the developer to optionally specify a compensation and confirmation activity to schedule appropriate business logic in the event of errors or successful completion of the Body. Compensation and confirmation of a CompensableActivity is invoked by using the CompensationToken returned by the CompensableActivity. CompensationToken is an opaque, typed object returned as the P:System.Activities.WorkflowElement`1.Result argument after successful completion of a CompensableActivity activity’s Body. This CompensationToken is used by the Confirm and Compensate activities to explicitly invoke confirmation and compensation of a CompensableActivity. CompensableActivity can be composed in a nested hierarchical fashion in the workflow. For more information, seeCompensation Programming Model.
