Unity Ioc配置错误

我有以下问题:

我使用IOC Unity和c#。实现IOC的情况如下:

using Microsoft.Practices.Unity;
using Microsoft.Practices.Unity.Configuration;
    namespace TansPritr.Ioc
    {
        public class IocContainer
        {
            private static readonly IocContainer contenedor = new IocContainer();
            private readonly IUnityContainer unityContainer;
            private IocContainer()
            {
                unityContainer = new UnityContainer();
                unityContainer.LoadConfiguration("miContenedor");
            }
            public static IocContainer Contenedor
            {
                get { return contenedor; }
            }
            /// <summary>
            ///   Create an instance of an object which implements TServicio.
            /// </summary>
            /// <typeparam name = "TServicio">Type of service which we want to resolve</typeparam>
            /// <returns></returns>
            public TServicio Resolver<TServicio>() where TServicio : class
            {
                return unityContainer.Resolve<TServicio>();
            }
        }
    }

我的App.Config如下:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
        <section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
      <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration"/>
    </configSections>
  <unity>
    <container>
      <register type="TransPritr.Interfaz.INegocio, TransPritr.Interfaz" mapTo="TransPritr.Buisness.Negocio, TransPritr.Buisness"/>
      <register type="TransPritr.Interfaz.ISqlServer,TransPritr.Interfaz" mapTo="TransPritr.DataAcces.SqlServer, TransPritr.DataAcces"/>
    </container>
  </unity>
</configuration>

现在，例如类Negocio如下:

using TransPritr.Interfaz;
namespace TransPritr.Buisness
{
    public class Negocio : INegocio
    {
        //private Collection<string[]> GetAllTransPritr()
        //{
        //    //var dataControl = IocContainer.Contenedor.Resolver<ISqlServer>();
        //   // return dataControl.GetAllTransPritr();
        //    return new Collection<string[]>();
        //}
        //private void CreateFile(Collection<string[]> lista)
        //{
        //    var filename = ConfigurationManager.AppSettings["FileName"];
        //    StreamWriter write = new StreamWriter(filename);
        //    int cont = 1;
        //    foreach (var linea in lista)
        //    {
        //        string temp = cont.ToString() + "|";
        //        foreach(var texto in linea)
        //        {
        //            temp += texto + "|";
        //        }
        //        write.WriteLine(temp);
        //    }
        //}
        public void Load()
        {
            //var lista = GetAllTransPritr();
           // CreateFile(lista);
        }
    }
}

它的界面是:

namespace TransPritr.Interfaz
{
    public interface INegocio
    {
        void Load();
    }
}

我的问题是，当我试图通过IOC与var interfaz = IocContainer.Contenedor.Resolver<INegocio>();调用Negocio类时，它给了我以下问题:

问题是我基于做工作的早期项目，但现在我在一个新项目中实现它，它不起作用。我不知道为什么，需要帮助。
