我是ASP .NET MVC的新手。我尝试使用实体框架，但它失败了，因为它没有找到EF。我搜索一个解决方案，并在另一篇文章中说我必须更改版本。我做了，但没有成功。

的Web.config：

  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.1.2.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <connectionStrings>
    <!--<add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-SportsStore.WebUI-20150201211232;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-SportsStore.WebUI-20150201211232.mdf" />-->
    <!--<add name="EFDbContext" providerName="System.Data.SqlClient" connectionString="Data Source=(localDb)\v11.0;Initial Catalog=SportsStore;Integrated Security=True" />-->
    <add name="EFDbContext" providerName="System.Data.SqlClient" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-SportsStore.WebUI-20150201211232;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-SportsStore.WebUI-20150201211232.mdf" />
  </connectionStrings>

这是浏览器的错误。

这就是break的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SportsStore.Domain.Abstract;
using SportsStore.Domain.Entities;

namespace SportsStore.Domain.Concrete
{
    public class EFProductRepository : IProductsRepository
    {
        private EFDbContext context = new EFDbContext();

        public IQueryable<Product> Products {
            get { return context.Products; }
        }
    }
}

EFDbContext.cs类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SportsStore.Domain.Entities;
using System.Data.Entity;

namespace SportsStore.Domain.Concrete
{
    public class EFDbContext : DbContext
    {
        public DbSet<Product> Products { get; set; }
    }
}
