我正在使用.Net Core 2.0和MySQL DB开发WEB API。我正在尝试搭建MySQL DB。我已经按照这个链接(MySQL官方网站)的说明进行操作,但是在执行搭建命令时,我遇到了下面两种错误,请告诉我是否有做错什么。
搭建命令(在程序包管理器控制台中运行):
Scaffold-DbContext "server=localhost;port=3306;user=root;password=darshan7826;database=sakila" MySql.Data.EntityFrameworkCore -OutputDir sakila -f
执行上述命令时出错

throw new NotImplementedException();
这个实现方式还是比较“标准”的。 - Ivan Stoev
