本文详细介绍了如何在服务端和客户端使用Castle Windsor容器管理WCF服务，通过配置windsor.xml实现服务注册与依赖注入，同时展示了针对transient生命周期管理的WCF通道关闭策略。

服务端windsor.xml:
<configuration><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

<facility id="wcf"

type="Castle.Facilities.WcfIntegration.WcfFacility,

Castle.Facilities.WcfIntegration" />

</facilities>

<component

id="order service"

service="WCF.Contract.ServiceContract.IOrder, WCF.Contract"

type="WCF.Service.OrderService, WCF.Service" >

</component>

</components>

</configuration>

服务端Global.asax

protected void Application_Start(object sender, EventArgs e)

{

Container = new WindsorContainer()

        .AddFacility<WcfFacility>()

        .Install(Configuration.FromXmlFile("Windsor.xml"));

}

服务端 Svr文件:

<% @ServiceHost Service="order service"

Factory="Castle.Facilities.WcfIntegration.DefaultServiceHostFactory, Castle.Facilities.WcfIntegration" %>

客户端windsor.xml

<facility id="wcf"

type="Castle.Facilities.WcfIntegration.WcfFacility,

Castle.Facilities.WcfIntegration" />

</facilities>

<component

id="order service"

type="WCF.Contract.ServiceContract.IOrder, WCF.Contract"

wcfEndpointConfiguration="order service" lifestyle="transient">

</component>

</components>

</configuration>

这里为了每次都要启动一个实例，采用了transient的对象生命周期，
但是默认的WcfManagedChannelInterceptor不会自动调用IChannel.Close()，所以我改了下WcfManagedChannelInterceptor 的代码，添加了
Close方法：
#region IInterceptor Members
public void Intercept(IInvocation invocation)
  {
   EnsureOpenChannel(invocation);
   invocation.Proceed();
            Close(invocation);
  }

#endregion

        void Close(IInvocation invocation)
        {
            if (lifestyle == LifestyleType.Transient)
            {
                IChannel channel = invocation.InvocationTarget as IChannel;
                if (channel != null)
                {
                    WcfUtils.ReleaseCommunicationObject(channel);
                }
            }
        }

这样的话每次调完一个wcf的实例，就把他关了
