WSE3 Web service call returns good SOAP but proxy returns null

i'm trying web service run inside regular windows service, using technique seems pretty documented, e.g.  http://geekswithblogs.net/marcel/archive/2007/04/02/110610.aspx.

 

when run client, i've tried generating using both wsewsdl3.exe , wsdl.exe, null string back.

 

webservice code:

    [webservice(namespace = "http://mynamespace.whatever")]      [webservicebinding(conformsto = "wsiprofiles.basicprofile1_1")]      public class mywebservice : webservice      {          [webmethod]          public string helloworld() {              console.writeline("received request hello.");              return "hello world";          }      }

my proxy, generated using wse3 version of exe:

    [system.codedom.compiler.generatedcodeattribute("wsdl", "2.0.50727.42")]      [system.diagnostics.debuggerstepthroughattribute()]      [system.componentmodel.designercategoryattribute("code")]      [system.web.services.webservicebindingattribute(name="servicesoap", namespace=http://mynamespace.whatever)]      public partial class service : microsoft.web.services3.webservicesclientprotocol {

    ...                    [system.web.services.protocols.soapdocumentmethodattribute(http://mynamespace.whatever/helloworld, requestnamespace="http://mynamespace.whatever", responsenamespace="http://mynamespace.whatever", use=system.web.services.description.soapbindinguse.literal, parameterstyle=system.web.services.protocols.soapparameterstyle.wrapped)]          public string helloworld() {              object[] results = this.invoke("helloworld", new object[0]);              return ((string)(results[0]));          }

here's soap envelope returned client looks like:

<soap:envelope xmlns:xop="http://www.w3.org/2004/08/xop/include"   	xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing"   	xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"   	xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"   	xmlns: soap="http://schemas.xmlsoap.org/soap/envelope/">  <soap:header>  </soap:header>  <soap:body>  <helloworldresponse   	xmlns:xsi=http://www.w3.org/2001/xmlschema-instance   	xmlns:xsd="http://www.w3.org/2001/xmlschema"   	xmlns ="http://mynamespace.whatever">  <helloworldresult>  hello world</helloworldresult>  </helloworldresponse>  </soap:body>  </soap:envelope>  
  

does have ideas why proxy wouldn't able parse response?
