System.Workflow.Runtime Namespace

Contains classes and interfaces that you can use to control the workflow runtime engine and the execution of a workflow instance.

The System.Workflow.Runtime namespace contains the WorkflowRuntime class, which you can use to configure, control, and subscribe to events for the workflow runtime engine associated with your application domain. The WorkflowInstance class provides a proxy to each workflow instance and lets you control the execution of a workflow. In addition to these classes, several classes having to do with workflow event queues and with exceptions thrown by the workflow runtime engine are contained in this namespace.
