VS 2013 EF6

维护一个老项目，需要添加数据库，添加得了EF6引用后，Install-Package EntityFramework -Version 6.1.1，项目右键添加ADO.Net Entity Data Model，出现如下问题：Your project references the latest version of Entity Framework; however, an Entity Framework database provider compatibale with this version could not be found for your data connectino.

就是找不到合适的data connetor，需要手动添加：添加引用 MySQL.Data，MySQL.Data.Entity.EF6

修改Config

<entityFramework>   
    <defaultConnectionFactory type="MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6" />
    <providers>
      <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" />
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>

重新编译项目，然后再添加就可以了
