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>

3、完事！！ 注意红色高亮处哦
