如何使用autofac注入到wcf类中？

[玩编程的小白]

大概是这样的代码

 public class DX : IDX
    {
        private readonly IDicDefService _dicdefsservice;
        public DX(IDicDefService _dicdefsservice)
        {
            this._dicdefsservice = _dicdefsservice;
        }
}

如果是一般的类，这样做没问题。
但DX是WCF服务类，不允许出现带参数的构造方法，所以不成立。
各位老鸟我该怎么办？
一个变通的方法是在构造函数里注入
类似这样的代码

 
public class DX : IDX
    {
        private readonly IDicDefService _dicdefsservice;
        public DX()
        {
            var builder = new ContainerBuilder();
            builder.RegisterType<DicDefService>().As<IDicDefService>();
           
             var container = builder.Build();
             _dicdefsservice=container.Resolve<DicDefService>();
        }
    }

这样写也不对，会报错
The requested service 'Estar.Base.Services.DicDefService' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

DicDefService类是这样的内容：

 private readonly IRepositoryBase<Models_DicDefRecord> _repositoryBase;
       
        public DicDefService(IRepositoryBase<Models_DicDefRecord> _repositoryBase)
        {
            this._repositoryBase = _repositoryBase;

        }

引入Autofac.Integration.Wcf; 在OnStart中

#region 注册各种
var builder = new ContainerBuilder();

builder.RegisterType<PetaPocoUnitOfWork>().As<IUnitOfWork>().InstancePerRequest();
builder.RegisterAssemblyTypes(Assembly.Load("Att.Implement")).Where(p => p.Name.EndsWith("Repository")).AsImplementedInterfaces();
builder.RegisterType<AttService>().As<IAttService>();

container = builder.Build();
DIContainer.Initialize(container);

if (host != null)
    host.Close();
host = new ServiceHost(typeof(AttService));
//重要
host.AddDependencyInjectionBehavior<IAttService>(container);

host.Open();
LoggerFactory.GetLogger().Error("服务已经启动");
#endregion

请参考 https://code.google.com/p/autofac/wiki/WcfIntegration

没有找到 AddDependencyInjectionBehavior 方法
