    web invocation result is null for webservice emulation

    I have a problem with the way that the generated proxy handles the
    information when trying to return information from an emulated
    webservice.

    When trying to consume the emulated service, the method result is
    always null, but for other (simple) types it works (ie with string).

    The problem is that there is no way to debug the Invoke method in
    Visual Studio and so I can't see what is happening. It should work!


    Below is the returned xml info from the (emulated) webservice;
    inspected with a proxy inspector:


    <soap:Envelop e xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http ://www.w3.org/2001/XMLSchema" xmlns:soap="htt p://
    schemas.xmlsoap .org/soap/envelope/">
    <soap:Body>
    <getAllServiceC onfigurationsRe sponse xmlns="http://nxp.com/
    ACSTopi.Service s.wsdl">
    <getAllServiceC onfigurationsRe sult>
    <BOM_Infrastruc ture_ESB_ISOESB RuntimeConfigur ation
    type="ACSTopi.A PI.Business.BOM .Infrastructure .ESB.ISOESBRunt imeConfiguratio n"
    assembly="ACSTo pi.API.Business .BOM" instance-
    id="b39322e1-79e6-4b2d-82e1-77a798b18ae9" object-id="88">
    <Serialized>
    ...xml info goes here
    </Serialized>
    </BOM_Infrastruct ure_ESB_ISOESBR untimeConfigura tion>
    </getAllServiceCo nfigurationsRes ult>
    </getAllServiceCo nfigurationsRes ponse>
    </soap:Body>
    </soap:Envelope>

    Worth noting: The proxy knows the structure of the objects
    (BOM_Infrastruc ture_ESB_ISOESB RuntimeConfigur ation) and generates the
    correct proxy objects.

    The overall communication runs, it's just the result returned is null.


    Does anybody know what is happening, or can suggest a solution.

      A null return usually means a namespace mismatch. The server is sending data
      in a different XML namespace than expected by the client.
