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!   ps: 注意首先要在生成的空数据库里建一个EdmMetadata表。
