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

 1 namespace DataModel.Migrations

 2 {

 3     using System;

 4     using System.Data.Entity;

 5     using System.Data.Entity.Migrations;

 6     using System.Linq;

 7 

 8     internal sealed class Configuration : DbMigrationsConfiguration<DataModel.SpaceDataContext>

 9     {

10         public Configuration()

11         {

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  

17         }

18 

19         protected override void Seed(DataModel.SpaceDataContext context)

20         {

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

22 

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

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

25             //

26             //    context.People.AddOrUpdate(

27             //      p => p.FullName,

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

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

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

31             //    );

32             //

33         }

34     }

35 }

 

2、修改 App.config 文件 entityFramework 节点

1   <entityFramework>

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

3     <contexts>

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

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

6       </context>

7     </contexts>

8   </entityFramework>

 

3、完事！！ 注意红色高亮处哦
