Using Mysql with asp.net core

I have a big project with MYSQL (Ado.net and entity framework).  I followed this guide:

http://dan.cx/2015/08/entity-framework-6-mysql-aspnet

Now i'm having problems moving to Asp.Net Core .Here are some errors i'm getting:

The type 'DbCommand' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. 

The type or namespace name 'DataSet' could not be found (are you missing a using directive or an assembly reference?)

The type or namespace name 'MySqlProviderServices' could not be found (are you missing a using directive or an assembly reference?) 

Is there any way to make mysql connector work ?  Does anyone know when oracle will release a connector for entity framework 7 ?
