Question

我开发了一个使用Agatha RRSL的WCF服务库，但我无法弄清楚如何初始化容器。如果我在ASP.NET Web应用程序中重新创建此服务，我可以从Global.asax.cs Application_Start（）调用初始化代码，一切都很完美。初始化代码是：

public static class ComponentRegistration
{
    public static void Register()
    {
      new ServiceLayerConfiguration(Assembly.GetExecutingAssembly(),
      typeof(HelloWorldRequest).Assembly,
      typeof(Agatha.Castle.Container)).Initialize();
    }
}

在WCF服务库中，我添加了一个App_Code文件夹，其中包含一个调用：

的类

public static void AppInitialize()
{
    ComponentRegistration.Register();
}

这不起作用，因为我的客户端应用程序抛出了一个异常，即该类型没有响应。我也尝试在web.config文件中添加一个组件，但我从来没有接受过工作。

我还尝试创建一个执行初始化的自定义ServiceHost：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ServiceModel;
using System.ServiceModel.Activation;
using Agatha.ServiceLayer;
using System.Reflection;
using Sample.Common.RequestsAndResponses;

namespace Sample.ServiceLayer.WCFHost
{
    public class CustomServiceHostFactory : ServiceHostFactory
    {
        public CustomServiceHostFactory()
        {
            new ServiceLayerConfiguration(Assembly.GetExecutingAssembly(), typeof(HelloWorldRequest).Assembly,
                typeof(Agatha.Castle.Container)).Initialize();
        }

        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
            return new CustomServiceHost(serviceType, baseAddresses);
        }
    }

    public class CustomServiceHost : ServiceHost
    {
        public CustomServiceHost()
        {
        }

        public CustomServiceHost(Type serviceType, params Uri[] baseAddresses)
            : base(serviceType, baseAddresses)
        {
        }

        protected override void OnOpening()
        {
            base.OnOpening();
        }

        protected override void OnClosing()
        {
            base.OnClosing();
        }

        protected override void ApplyConfiguration()
        {
            base.ApplyConfiguration();
        }
    }
}

但是，我的客户端也遇到了同样的异常：

System.InvalidOperationException was unhandled
  Message=There is no response with type Sample.Common.RequestsAndResponses.HelloWorldResponse. Maybe you called Clear before or forgot to add appropriate request first.

  InnerException:

我应该采取什么方法让WCF服务库运行我的初始化代码，以便主机返回正确的类型？任何指导都将非常感谢。感谢。
