ListenUriMode Enumeration

Indicates whether the transport must ensure that the URI provided for the service to listen on is unique or can be used exactly as provided.

Namespace: System.ServiceModel.Description
Assembly: System.ServiceModel (in system.servicemodel.dll)

public enum ListenUriMode
public enum ListenUriMode
public enum ListenUriMode

 Member nameDescription
ExplicitUses the ListenUri exactly as provided. This is the default value. 
UniqueSpecifies that the transport should use a transport-specific mechanism to ensure that the ListenUri is unique. 

The URI for the endpoint on which a service listens can be set programmatically using the ListenUri property and the value of the ListenUriMode for that endpoint is set using the ListenUriMode property. The default value for ListenUri is Address. The default value for ListenUriMode is Explicit.

The value of these properties may also be set using the ListenUri property and the ListenUriMode property.

When the value of the ListenUriMode is set to Unique the transport is responsible for creating a unique URI. Different transports used by Windows Communication Foundation (WCF) generate this unique URI differently

  • For TCP in exclusive mode (PortSharingEnabled is false) this means binding to a uniquely available port number.

  • For TCP in port sharing mode (PortSharingEnabled is true) and for all of the other existing WCF transports, this means appending a unique path (a GUID) to the end of the ListenUri.

When the value of the ListenUriMode is set to Explicit mode, the transport uses the ListenUri exactly as it is provided, without modifying it to make it unique.
