MVC DBMigration

1. MVC里自己建立数据库访问，出现数据库错误：
   Model compatibility cannot be checked because the database does not contain
   model metadata. Model compatibility can only be checked for databases created
   using Code First or Code First Migrations.
   百度无果，隔日Google英文~~
   解决方案：
   command in Package Manager Console.
   1.PM>Enable-Migrations
   或者还可以：
   
   
   2.PM> add-migration Initial
       
   3.PM> Update-Database
   
   问题搞定，生成数据库，还是国外程序员牛逼！
