Both OnUnhandledException and WorkflowUnhandledExceptionBehavior dictate the behavior of the runtime when an exception is not handled in the workflow; however, WorkflowUnhandledExceptionBehavior has the option of leaving a suspended workflow in the persistence store, while OnUnhandledException does not. The reason for this is that what happens to a suspended workflow is host-specific, and WorkflowApplication is not. To implement this functionality using WorkflowApplication, create a custom PersistenceParticipant that has this behavior.

For an example of how to use this behavior see Workflow Service Host Extensibility.
