In SOAP message to WCF web service, how to put KeyIdentifier directly inside SecurityTokenReference (inline, without using Reference token)

问题

I'm successful in communicating with a WCF service via SoapUI (I was given specification on how to configure it), but I'm having trouble in copying those settings to .NET application. Turns out the shape of generated SOAP message (peeked via Fiddler) is being rejected by the web service, who expects a stricter layout of envelope.

I'm very close. On this picture...

... you can see three SOAP messages:

1. With X509SecurityTokenParameters.InclusionMode set to AlwaysToRecipient

2. With X509SecurityTokenParameters.InclusionMode set to Never

3. Expected security token, tested on SoapUI.

How do I achieve envelope from point 3 using C# code? I'm not using app.config file, entire config is inside C# code (but I'm not dedicated on keeping it that way, it just happened). Current code:

using System;
using System.Net;
using System.Security.Cryptography.X509Certificates;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.ServiceModel.Security;
using System.ServiceModel.Security.Tokens;
using System.Text;

I ended up using InclusionMode = SecurityTokenInclusionMode.Never, then hijacked the message and replaced incorrect tags manually.

public class CustomProxy_portClient : GeneratedProxy_portClient
{
    public CustomProxy_portClient() : base()
    {
        Endpoint.Behaviors.Remove(typeof(ClientCredentials));
        Endpoint.Behaviors.Add(new CustomClientCredentials());
    }
}



class CustomClientCredentials : ClientCredentials
{
    public CustomClientCredentials() : base() { }
    public CustomClientCredentials(ClientCredentials ClientCredentials) : base(ClientCredentials) { }

    public override SecurityTokenManager CreateSecurityTokenManager()
    {
        return new CustomSecurityTokenManager(this);
    }

    protected override ClientCredentials CloneCore()
    {
        return new CustomClientCredentials(this);
    }
}



class CustomSecurityTokenManager : ClientCredentialsSecurityTokenManager
{
    public CustomSecurityTokenManager(ClientCredentials clientCredentials) : base(clientCredentials) { }

    public override SecurityTokenSerializer CreateSecurityTokenSerializer(SecurityTokenVersion version)
    {
        return new CustomWSSecurityTokenSerializer();
    }
}



class CustomWSSecurityTokenSerializer : WSSecurityTokenSerializer
{
    protected override void WriteKeyIdentifierClauseCore(XmlWriter writer, SecurityKeyIdentifierClause keyIdentifierClause)
    {
        string xml;
        using(MemoryStream ms = new MemoryStream())
        {
            XmlTextWriter tempWriter = new XmlTextWriter(ms, new UTF8Encoding(false));
            base.WriteKeyIdentifierClauseCore(tempWriter, keyIdentifierClause);
            xml = Encoding.UTF8.GetString(ms.ToArray());
        }
        XmlDocument originalKeyIdentifierClause = new XmlDocument();
        originalKeyIdentifierClause.LoadXml(xml);

        writer.WriteStartElement("SecurityTokenReference");
        writer.WriteElementString("KeyIdentifier", originalKeyIdentifierClause.InnerText);
        writer.WriteEndElement();
    }
}
