WorkflowInstance::OnRequestAbort Method

Called by the workflow runtime to notify the host that an abort operation has been requested for the workflow instance.

Namespace:  System.Activities.Hosting
Assembly:  System.Activities (in System.Activities.dll)

protected public:
virtual void OnRequestAbort(
	Exception^ reason
) abstract


Type: System::Exception
The reason for aborting the workflow instance.

Once OnRequestAbort(Exception) is called, most WorkflowInstance::WorkflowInstanceControl APIs except Abort() will throw an InvalidOperationException. It is expected that after OnRequestAbort(Exception) is called a host will trend toward a state in which it can satisfy the abort.
