1、修改 Migrations/Configuration.cs 文件

 namespace DataModel.Migrations

 {

     using System;

     using System.Data.Entity;

     using System.Data.Entity.Migrations;

     using System.Linq;

     internal sealed class Configuration : DbMigrationsConfiguration<DataModel.SpaceDataContext>

     {

         public Configuration()

         {

12             AutomaticMigrationsEnabled = true;

13

14             AutomaticMigrationDataLossAllowed = true;

15

16             SetSqlGenerator("MySql.Data.MySqlClient", new MySql.Data.Entity.MySqlMigrationSqlGenerator());    // This will add our MySQLClient as SQL Generator

         }

         protected override void Seed(DataModel.SpaceDataContext context)

         {

             //  This method will be called after migrating to the latest version.

             //  You can use the DbSet<T>.AddOrUpdate() helper extension method

             //  to avoid creating duplicate seed data. E.g.

             //

             //    context.People.AddOrUpdate(

             //      p => p.FullName,

             //      new Person { FullName = "Andrew Peters" },

             //      new Person { FullName = "Brice Lambson" },

             //      new Person { FullName = "Rowan Miller" }

             //    );

             //

         }

     }

 }

2、修改 App.config 文件 entityFramework 节点

   <entityFramework>

     <defaultConnectionFactory type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data" />

     <contexts>

       <context type="DataModel.SpaceDataContext,DataModel">

         <databaseInitializer type="System.Data.Entity.MigrateDatabaseToLatestVersion`2[[DataModel.SpaceDataContext,DataModel], [DataModel.Migrations.Configuration,DataModel]], EntityFramework" />

       </context>

     </contexts>

   </entityFramework>

3、完事！！ 注意红色高亮处哦
