[Mono-list] Hosting WCF WebHttpBinding in XSP?

I'm trying to host a WCF service that uses the WebHttpBinding in XSP.

This is based on an adaptation of one of the Mono WCF samples by Atsushi
Eno here:

Specifically, my modified code looks like (modified to use a UriTemplate):

// service
using System;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.ServiceModel.Description;
using System.ServiceModel.Dispatcher;
using System.ServiceModel.Web;

public interface IMyService
  [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/greet/{input}")]
  string Greet (string input);

public class MyService : IMyService
  public string Greet (string input)
    return "hola, " + input;

public class Test
  public static void Main ()
    string url = "http://localhost:8080/";
    WebHttpBinding b = new WebHttpBinding ();
    var host = new WebServiceHost (typeof (MyService), new Uri (url));
    host.AddServiceEndpoint (typeof (IMyService), b, "");
    host.Open ();
    Console.WriteLine ("--- type [CR] to quit ---");
    Console.ReadLine ();
    host.Close ();

This works great, and I can query the service at this URL:
http://localhost:8080/greet/name, which responds with "hello, name".

Next I built it as a library and created an svc file that contains:

<%@ServiceHost Service="MyService" %>

Then a web.config with:

<?xml version="1.0" encoding="utf-8" ?>
      <service name="WcfServiceLibrary1.Service1">
        <endpoint address="" binding="webHttpBinding" contract="IMyService"

However, when I start xsp and try to query:
http://localhost:8080/service.svc/greet/name, I get back a
System.InvalidOperationException, with the error message
"HttpListenerContext does not match any of the registered channels".

I've been trying a few different things along these lines, but this so far
has been the most simple test code I have yet.

Is this something that should be supported in xsp? It seems to work fine in
a stand-alone Mono executable, but I would like to host this along side
some HTML pages without using IIS (which is why I am starting with xsp,
perhaps later Apache and mod_mono if I could get xsp working first).

I have been trying this both on a Debian host (Mono 4.2.4) and a Windows 7
host (Mono 4.4.1); both yield the same issues (HttpListenerContext does not
match any of the registered channels).

Thanks in advanced for any guidance..
