WorkflowServiceHost.OnClose Method

Closes down the hosted service, including the channel dispatchers and associated instance contexts and listeners.

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

abstract OnClose : 
        timeout:TimeSpan -> unit 
override OnClose : 
        timeout:TimeSpan -> unit 


Type: System.TimeSpan
The period of time the close operation has to complete before timing out.

The workflow runtime will try to persist any hosted workflow when OnClose(TimeSpan) is called, but persistence is not guaranteed in this scenario. If important business data is being hosted, the instances should persist frequently (such as after each Send operation, or after an interval of time) to ensure that data is not lost.
