右击已有的C#工程，然后选择 Add New Item，在 Visual C# Items->Data栏目中看看有没有ADO.NET Entity Data Model选项，如果没有则还没有安装该模板；或你也可以在VS安装目录下看看C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplates\CSharp\Data\1033\AdoNetEntityDataModelCSharp.zip 该文件存在不存在，如果不存在则需要安装该模板。如何安装呢，插入VS安装盘，选择修复，选中该组件安装就可以了。

3，使用MySQL workbench在 MySQL表中新建数据库 EFSample，在其中新建表customer，该表包含三个字段 id, Address, Name。如下所示：

4，新建C#控制台程序 EFSample，然后右击工程名，然后选择 Add New Item，在 Visual C# Items->Data中选择ADO.NET Entity Data Model，命名为 EFSampleModel.edmx：

然后选择从数据库生成：

然后设置New Connection，选择MySQL Provider，如下所示：

选择要映射的数据库与表，并将模型命名为EFSampleModel：

至此，我们就能够在工程中看到创建的EFSampleModel.edmx：

5，我们可以使用xml编辑打开 EFSampleModel.edmx，在这个文件中定义了SSDL content，CSDL content以及 C-S mapping content。同样，EF为我们自动生成了与数据库对于的运行时类，这些类被定义在EFSampleModel.Designer.cs文件中，其中有对customer类的定义。该类定义了一个工程方法，我们可以使用该工厂方法来生成 customer 对象。

    /// <summary>
    /// No Metadata Documentation available.
    /// </summary>
 [EdmEntityTypeAttribute(NamespaceName="EFSampleModel", Name="customer")]
    [Serializable()]
    [DataContractAttribute(IsReference=true)]
    public partial class customer : EntityObject
    {
        #region Factory Method
    
        /// <summary>
        /// Create a new customer object.
        /// </summary>
        /// <param name="address">Initial value of the Address property.</param>
        /// <param name="id">Initial value of the id property.</param>
        /// <param name="name">Initial value of the Name property.</param>
 public static customer Createcustomer(global::System.String address, global::System.Int64 id, global::System.String name)
        {
            customer customer = new customer();
            customer.Address = address;
            customer.id = id;
            customer.Name = name;
            return customer;
        }

        #endregion
    }

6，新建 customer的部分类来添加对象的描述：

namespace EFSample
{
    public partial class customer : global::System.Data.Objects.DataClasses.EntityObject
    {
        override public string ToString()
        {
            return string.Format("Customer Name: {0}, Address: {1}", this.Name, this.Address);
        }
    }
}

7，支持大部分配置工作完成，下面开始编写与数据库进行交互相关的代码。修改 Program.cs为：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;

namespace EFSample
{
    class Program
    {
        const int MaxRow = 10;

        static void DeleteData()
        {
            using (var ctx = new EFSampleEntities())
            {
                var customers = from c in ctx.customer select c;
                foreach (customer c in customers)
                {
                    ctx.DeleteObject(c);
                }

                ctx.SaveChanges();
            }
        }

        static void InsertData(customer[] cs)
        {
            using (var ctx = new EFSampleEntities())
            {
                foreach (customer c in cs)
                {
                    ctx.AddTocustomer(c);
                }

                ctx.SaveChanges();
            }
        }

        static void QueryData()
        {
            using (var ctx = new EFSampleEntities())
            {
                for (int i = 1; i <= MaxRow; i++)
                {
                    String str = i.ToString();
                    var results = ctx.customer.Where(c => c.Address == str);
                    foreach (customer c in results)
                    {
                        Console.WriteLine(c);
                    }
                }
            }
        }

        static void Main(string[] args)
        {
            customer[] cs = new customer[MaxRow];
            for (int i = 1; i <= MaxRow; i++)
            {
                StringBuilder sb = new StringBuilder();
                sb.Append("用户");
                sb.Append(i);
                customer c = customer.Createcustomer(i.ToString(), i, sb.ToString());

                cs[i - 1] = c;
            }

            Console.WriteLine("=================== TEST START ===================");

            DeleteData();

            Console.WriteLine(">> Storage test start...");
            Stopwatch sw = Stopwatch.StartNew();

            InsertData(cs);

            sw.Stop();
            Console.WriteLine("<< Store data seconds: " + sw.ElapsedMilliseconds / 1000 + " ( " + sw.ElapsedMilliseconds + " miliseconds)");

            Console.WriteLine(">> Query test start...");
            sw = Stopwatch.StartNew();

            QueryData();

            sw.Stop();
            Console.WriteLine("<< Query data seconds: " + sw.ElapsedMilliseconds / 1000 + " ( " + sw.ElapsedMilliseconds + " miliseconds)");

            Console.WriteLine(">> Delete test start...");
            sw = Stopwatch.StartNew();

            DeleteData();

            sw.Stop();
            Console.WriteLine(">> Delete data seconds: " + sw.ElapsedMilliseconds / 1000 + " ( " + sw.ElapsedMilliseconds + " miliseconds)");

            Console.WriteLine("Press any key to exit...");
            Console.ReadLine();
        }
    }
}
