RESOLVED: WSIT and WCF Jun CTP Interop Bug

Taking on from previous post ...

Even though the list of breaking changes from Feb CTP to Vista Beta 2 and Vista Beta 2 to Jun CTP are documented. The list is missing a "minor" detail of changing the WS-Addressing 1.0 WSDL Binding namespace from http://www.w3.org/2005/08/addressing (same as SOAP Binding namespace) to http://www.w3.org/2006/05/addressing/wsdl (WSDL Binding CR namespace). As a result a user reported interop problems between Jun CTP and WSIT.

I updated the namespace for WS-Addressing WSDL Binding in WSIT this morning. After deploying one of the JAX-WSA unit tests and invoking svcutil.exe to generate proxy, got the following warning:

Warning: The optional WSDL extension element 'UsingAddressing' from namespace 'http://www.w3.org/2006/05/addressing/wsdl' was not handled.
XPath: //wsdl:definitions[@targetNamespace='http://example.org/wsaTestService2']/wsdl:binding[@name='wsaTestPortTypeBindingAddressingRequired']

Seems like this CTP completely ignores a standard W3C extension element to indicate WS-Addressing on a binding/port. It generated the proxy correctly but of course the client did not send expected WS-Addressing headers and thus the endpoint faulted appropriately. Anyway, I specified UsingAddressing within a policy assertion, regenerated the proxy and invoked the client. The server returned the response correctly and CTP client displayed the response in console.

WSIT is now again interoperating with Jun CTP.
