使用ninject，异常。请大家帮忙看看

using System;using System.Collections.Generic;using System.Linq;using System.Text;using Ninject;namespace Test{    class Program    {        static void Main(string[] args)        {            IKernel ninjectKernal = new StandardKernel();            ninjectKernal.Bind<ICalculateHelper>().To<CalculateHelper>();            ICalculateHelper ic = ninjectKernal.Get<ICalculateHelper>();            CalculateHelper ch = new CalculateHelper(ic);            Console.WriteLine(ch.Add(1, 2).ToString());            Console.ReadKey();        }    }    public interface ICalculateHelper    {         decimal Add(decimal a, decimal b);         decimal Sub(decimal a, decimal b);    }    public class CalculateHelper:ICalculateHelper    {        private ICalculateHelper ic;        public CalculateHelper(ICalculateHelper icParam)        {            ic = icParam;        }        public decimal Add(decimal a, decimal b)        {            return b + a;        }        public decimal Sub(decimal a, decimal b)        {            return a - b;        }    }}

错误激活ICalculateHelper使用绑定从ICalculateHelper至CalculateHelperA循环依赖检测两个服务之间的构造函数。
