Remarks

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

Use the ServiceHost class to configure and expose a 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 ServiceHost object on your behalf.

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

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