Mysql 6.7.7 + EntityFramework 5.0 Code First 不能 Update-Database 问题的解决

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>
