HttpListenerHost tutorial?

[innes]

Hi, Does anyone have, or could they rustle up, a total beginner-level
piece of example code for using HttpListenerHost? Maybe even just a
console app that responds to requests to a single url - nothing
dynamic. I have had a go, but got hit by a 'pipeline not initialized'
exception whenever making any http request to the listener. I expect
that most people use OR in IIS, hence the lack of an example. Any help
is appreciated, thanks!

For more background, here's my test program, followed by the exception
that gets thrown when I try and GET http://localhost:9222/test.txt:

-----------------------------------------------
using System;
using OpenRasta.DI;
using OpenRasta.Hosting.HttpListener;
using OpenRasta.Configuration;

namespace ORConsole
{
public class TestHandler
{
public string Get() { return "hello world"; }
}

public class Configurator : IConfigurationSource
{
public void Configure()
{
ResourceSpace.Has
.ResourcesOfType<string>()
.AtUri("test.txt")
.HandledBy<TestHandler>()
.TranscodedBy<OpenRasta.Codecs.TextPlainCodec>();
}
}

public class HttpListenerHostWithConfiguration : HttpListenerHost
{
public IConfigurationSource Configuration { get; set; }

public override bool ConfigureRootDependencies(IDependencyResolver
resolver)
{
var result = base.ConfigureRootDependencies(resolver);
if (result && Configuration != null)
resolver.AddDependencyInstance<IConfigurationSource>
(Configuration);
return result;
}
}

public class Program
{
private static void Main()
{
var h = new HttpListenerHostWithConfiguration
{Configuration = new Configurator()};

h.Initialize(new[]{"http://+:9222/"}, "/", null);
h.StartListening();

Console.WriteLine("Press enter to exit.");
Console.ReadLine();
}
}
}

You haven't added the using (OpenRastaConfiguration.Manual) {} in your
configuration code

Thanks.
