1、首先需要从gitHub上下载源码：

https://github.com/aspnet/EntityFramework6

2、添加新项目，并且把EntityFramework 项目和EntityFramework.SqlServer添加的新添加的解决方案里

3、去掉EntityFramework和EntityFramework.SqlServer 中的签名

4、修改新项目的配置文件

<configuration>
  <configSections>
    <section name="entityFramework"
             type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral"
             requirePermission="false" />
  </configSections>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="v11.0" />
      </parameters>
    </defaultConnectionFactory>
    <providers>
      <provider invariantName="System.Data.SqlClient"
                type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
 
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
    </startup>
</configuration>

5、编写代码，使用CodeFirst模式调制程序

  public class TestDBDbContext:DbContext
    {
        public TestDBDbContext() : base("data source=127.0.0.1;initial catalog=TestDB;user id=sa;password=123456;multipleactiveresultsets=True;application name=EntityFramework")
        {

        }

        public virtual DbSet<TB_City> City { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            
        }
    }

[Table("TB_City")]
    public class TB_City
    {
        [Key]
        public int ID { get; set; }
        public string CityName { get; set; }
        public string ZipCode { get; set; }
        public int PrivinceID { get; set; }
    }

TestDBDbContext db = new TestDBDbContext();

        public void Create()
        {
            db.City.Add(new TB_City() { CityName = "济南", PrivinceID = 1, ZipCode = "200000" });

            db.SaveChanges();
        }

5、开始调用

 static void Main(string[] args)
        {
            CityDAL dal = new ConsoleApplication.CityDAL();
            dal.Create();

            Console.Read();
        }
