AddressingVersion Class

The WS-Addressing version associated with a SOAP message or understood by an endpoint.

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

Public NotInheritable Class AddressingVersion
Dim instance As AddressingVersion

There are currently two version of WS-Addressing: WS-Addressing August 2004 and WS-Addressing 1.0. These versions can be retrieved using the WSAddressingAugust2004 and WSAddressing10 properties, respectively. There is also an addressing version available that is not associated with WS-Addressing, which is retrieved using the None property. This value indicates that no version of WS-Addressing is used. This is primarily for transports that do not pass SOAP envelopes on the wire and therefore have no use for WS-Addressing.

The addressing version is part of the message version: specifically AddressingVersion provides the return type for the Addressing property. The MessageVersion also contains the SOAP envelope version in addition to the addressing version information. The EnvelopeVersion provides the return type for the Envelope property.
