IDataServiceHost Interface

Definition

Interface that specifies interactions between WCF Data Services and its hosting environment.

public interface class IDataServiceHost
public interface IDataServiceHost
type IDataServiceHost = interface
Public Interface IDataServiceHost
Derived

Remarks

Each component that hosts WCF Data Services, such as Windows Communication Foundation (WCF) must implement this interface. IDataServiceHost is the contract between WCF Data Services and its hosting environment. This abstraction allows the WCF Data Services runtime to be agnostic to any particular hosting environment. The interface provides WCF Data Services with access to inbound HTTP requests. A new object implementing this interface is instantiated for each HTTP request and is then used to inspect properties of the HTTP request and configure the HTTP response.
