c# - Autofac RegisterType中不提供EnableInterfaceInterceptors

我想使用Autofac探索自定义拦截器。我当前正在使用4.2.0版的Autofac和3.3.3版的Castle.Core用于DynamicProxy。

我从以下基本动作开始，希望在Autofac中使用其接口注册测试类：

using Autofac;
using Castle.DynamicProxy;

class Program
{
    static void Main(string[] args)
    {
        ContainerBuilder builder = new ContainerBuilder();
        builder.RegisterType<MyClassA>()
            .As<IMyInterface>()
            .EnableInterfaceInterceptors()
            .InterceptedBy(typeof(MyInterceptor));
        builder.RegisterType<MyInterceptor>().AsSelf();
        var container = builder.Build();
    }
}

问题是“ .EnableInterfaceInterceptors（）”行在其下面有一条红色的错误弯曲的行，带有以下错误：

'IRegistrationBuilder<MyClassA, ConcreteReflectionActivatorData, SingleRegistrationStyle>' does not contain a definition for 'EnableInterfaceInterceptors' and no extension method 'EnableInterfaceInterceptors accepting a first argument of type 'IRegistrationBuilder<MyClassA, ConcreteReflectionActivatorData, SingleRegistrationStyleA>' could be found (are you missing a using directive or an assembly reference?)

到目前为止（如果相关）其他组件的代码是：

public interface IMyInterface
{
    void DoWork(string key1, string key2);
}


using System;

public class MyClassA : IMyInterface
{
    public void DoWork(string key1, string key2)
    {
        Console.WriteLine(string.Format("A: {0} - {1}", key1, key2));
    }
}


using System;
using Castle.DynamicProxy;

public class MyInterceptor : StandardInterceptor
{
    protected override void PreProceed(IInvocation invocation)
    {
        Console.Write("PreProceed:  ");
    }
}

有人可以告诉我为什么.EnableInterfaceInterceptors()不起作用吗？
