DiscoveryServiceExtension Class

An abstract WCF extension class for specifying a custom discovery service or for getting the published endpoints.


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

public abstract class DiscoveryServiceExtension : IExtension<ServiceHostBase>

The DiscoveryServiceExtension type exposes the following members.

Protected methodDiscoveryServiceExtensionInitializes a new instance of the DiscoveryServiceExtension class.

Public propertyPublishedEndpointsGets a read-only collection of published endpoints.

Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Protected methodGetDiscoveryServiceOverride this method to return your custom DiscoveryService implementation.
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Explicit interface implemetationPrivate methodIExtension<ServiceHostBase>.AttachAttaches the extension to the specified service host.
Explicit interface implemetationPrivate methodIExtension<ServiceHostBase>.DetachOverload this method to allow the extension to be detached from its service host.

Derive a class from DiscoveryServiceExtension and override the GetDiscoveryService method to return your custom discovery service. Add your derived class to the ServiceHost extensions that host your discoverable service. When the Validate is called the behavior iterates through the extensions in the service host and looks for a DiscoveryServiceExtension. If one is found its GetDiscoveryService is called to get the custom discovery service. If an extension is not found the default discovery service implementation is used.
