WCF provides a number of standard bindings, each targeting a specific usage scenario. WSHttpBinding is for the mainline Internet web services scenario. It uses the newer SOAP version 1.2 and WS-Addressing version 1.0 and enables a wide range of security settings over the public http/https transport. WWSAPI does not have an equivalence of the WSHttpBinding (or any of the WCF standard bindings), but since its default SOAP version, WS-Addressing version and encoding format match those in WSHttpBinding, interoperating between WWSAPI and WSHttpBinding is straightforward. For example, to use service proxy to talk to a WSHttpBinding endpoint without security, you only need to write the code like following snippet (variable declaration and heap/error creation omitted). Notice that no channel properties or security description is specified at WsCreateServiceProxy.
