protected public:
 abstract System::Workflow::ComponentModel::Activity ^ LoadCompletedContextActivity(Guid scopeId, System::Workflow::ComponentModel::Activity ^ outerActivity);

protected internal abstract System.Workflow.ComponentModel.Activity LoadCompletedContextActivity(Guid scopeId, System.Workflow.ComponentModel.Activity outerActivity);

abstract member LoadCompletedContextActivity : Guid * System.Workflow.ComponentModel.Activity -> System.Workflow.ComponentModel.Activity

Protected Friend MustOverride Function LoadCompletedContextActivity (scopeId As Guid, outerActivity As Activity) As Activity

Parameters

scopeId: Guid

The Guid of the completed scope.

outerActivity: Activity

An Activity that represents the activity that encloses the completed scope.

Returns

Activity

An Activity that represents the completed scope.

Remarks

The workflow runtime engine uses LoadCompletedContextActivity to implement compensation. You must restore an identical copy of the completed scope. To do this, you must restore a valid Stream from your representation of the completed scope in the data store. Then you must pass this Stream to one of the overloaded methods of Load to perform deserialization of the scope.

If your persistence service cannot load the completed scope from its data store, it should throw a PersistenceException with an appropriate message.
