WorkflowServiceHost Class

Provides host for workflow-based services.

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

public class WorkflowServiceHost : ServiceHostBase

Implements the host used by the Windows Communication Foundation (WCF) service model programming model.

Use the WorkflowServiceHost class to configure and expose a workflow as service for use by client applications when you are not using Internet Information Services (IIS) or Windows Activation Services (WAS) to expose a service. Both IIS and WAS interact with a WorkflowServiceHost object on your behalf.

To expose a workflow as service for use by callers, WCF requires a complete service description (represented by the ServiceDescription class). The WorkflowServiceHost class creates a ServiceDescription from the workflow service type and configuration information and then uses that description to create ChannelDispatcher objects for each endpoint in the description.

Use a WorkflowServiceHost object to load a workflow service, configure endpoints, apply security settings, and start listeners to handle incoming requests.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
