Provides a threading service that allows the host application creating a workflow instance to donate the on which the workflow instance is run. Using this threading service, host applications can run a workflow instance on a single in synchronous mode (although if the workflow contains a delay activity, the work is postponed until after the delay activity is executed on a separate thread spawned by ).This mode blocks the execution of the host application until the workflow instance becomes idle. Subsequently, the workflow instance can only be executed using the method of this service.
