Remarks

The MessageVersion contains the versioning information both about the SOAP envelope and the addressing protocol that is used by a message. An instance of Message is bound upon creation to a specific MessageVersion by passing the version as a parameter into one of the CreateMessage overloads.

All the static "get" properties in this class indicate the possible message versions supported by the Silverlight 5 runtime.

There are currently two SOAP envelope versions available: SOAP 1.1 and SOAP 1.2. These versions of SOAP are represented by EnvelopeVersion and are returned by the Soap11 and Soap12WSAddressing10 properties. The version of SOAP associated with the MessageVersion can be recovered by using the Envelope property.

For more information, see

the schema for SOAP 1.1 and SOAP 1.2.

There is currently one version of WS-Addressing supported by the Silverlight 5 runtime: the one specified in the WS-Addressing 1.0 protocol. The address version used by the current message version can be recovered using the Addressing property. The version of WS-Addressing is represented by AddressingVersion and is returned by the WSAddressing10 property. The 9 May 2006 W3C Recommendation for WS-Addressing 1.0 - Core is available at 9 May 2006 W3C WS-Addressing 1.0 - Core.

The None property provides support for using "plain old XML" (POX)-style messaging. Enabling basic POX messaging is now a matter of setting up an HTTP binding on your service with a text encoder that uses the None property.
