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
