OnRequestAbort Method

WorkflowInstance.OnRequestAbort Method (Exception)

.NET Framework 4.6 and 4.5

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 Friend MustOverride Sub OnRequestAbort (
	reason As Exception


Type: System.Exception

The reason for aborting the workflow instance.

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