The ADO.NET Data Services class derived from WebServiceHost used to instantiate data services.
Assembly: System.Data.Services (in System.Data.Services.dll)
ADO.NET Data Services are not autonomous server entities. Instead, the service is a component hosted in an environment such as the Windows Communication Foundation (WCF) that provides core server networking facilities. Specifically, a service does not bind to and listen on a network socket for incoming requests to its Representational State Transfer (REST) entry points. The host handles direct interactions with the network and support caching, scalability, and authentication modules.
ADO.NET Data Services defines a generic hosting interface IDataServiceHost that abstracts its implementation from a specific host. This allows ADO.NET Data Services to run in a range of hosting environments.
