I have been trying to port a legacy WSE 3 web service to WCF. Since maintaining backwards compatibility with WSE 3 clients is the goal, I've followed the guidance in this article.

After much trial and error, I can call the WCF service from my WSE 3 client. However, I am unable to add or update a web reference to this service from Visual Studio 2005 (with WSE 3 installed). The response is "The request failed with HTTP status 400: Bad Request". I get the same error trying to generate the proxy using the wsewsdl3 utility. I can add a Service Reference using VS 2008.

Any solutions or troubleshooting suggestions?

Here are the relevant sections from the config file for my WCF service.

<system.serviceModel>
    <services>
      <service behaviorConfiguration="MyBehavior"
        name="MyService">
        <endpoint address="" binding="customBinding" bindingConfiguration="wseBinding"
          contract="IMyService" />
        <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />
      </service>
    </services>

    <bindings>
      <customBinding>
        <binding name="wseBinding">
          <security authenticationMode="UserNameOverTransport" />
          <mtomMessageEncoding messageVersion="Soap11WSAddressingAugust2004" /> 
          <httpsTransport/>
        </binding>
      </customBinding>
    </bindings>

    <behaviors>
      <serviceBehaviors>
        <behavior name="MyBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
          <serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode="Custom"
              customUserNamePasswordValidatorType="MyCustomValidator" />
          </serviceCredentials>
          <serviceAuthorization principalPermissionMode="UseAspNetRoles" roleProviderName="MyRoleProvider" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
  </system.serviceModel>
