我正在尝试构建路由基础设施，并使用 Autofac 作为 IoC 容器。我阅读了wiki，并且知道以下步骤：

ContainerBuilder builder = new ContainerBuilder();
builder.Register(c => new Logger()).As<ILogger>();
builder.Register(c => new EchoService(c.Resolve<ILogger>())).As<IEchoService>();

using (IContainer container = builder.Build())
{
    Uri address = new Uri("http://localhost:8080/EchoService");
    ServiceHost host = new ServiceHost(typeof(EchoService), address);

host.AddServiceEndpoint(typeof(IEchoService), new BasicHttpBinding(), string.Empty);

host.AddDependencyInjectionBehavior<IEchoService>(container);

host.Description.Behaviors.Add(new ServiceMetadataBehavior {HttpGetEnabled = true, HttpGetUrl = address});
host.Open();

Console.WriteLine("The host has been opened.");
Console.ReadLine();

host.Close();
Environment.Exit(0);

}

我这里有这个代码来满足我的场景：

builder.RegisterType<RoutingService>().As<ISimplexDatagramRouter>().InstancePerLifetimeScope();

        builder.Register(c =>
        {
            var routingConfiguration = new RoutingConfiguration();
            routingConfiguration.RouteOnHeadersOnly = false;
            return routingConfiguration;
        }).As<RoutingConfiguration>();

        builder.Register(c =>
            {
                var publisherServiceHost = new ServiceHost(typeof(RoutingService));
                publisherServiceHost.AddServiceEndpoint(typeof(ISimplexDatagramRouter), new NetTcpBinding(), "some address");
                publisherServiceHost.Description.Behaviors.Add(new RoutingBehavior(c.Resolve<RoutingConfiguration>()));
                return publisherServiceHost;
            }).As<ServiceHost>();

这不起作用，因为我从 Autofac 收到错误，因为它找不到 RoutingService 的构造函数（它的构造函数是私有的）。

你有什么提示吗？

As far as I know the RoutingService class has no constructors defined. You can see that if you try to do this:

RoutingService rs = new RoutingService();

You will get an error from the compiler saying: The type System.ServiceModel.Routing.RoutingService has no constructors defined.
