脚手架-DbContext "The method or operation is not implemented"
Scaffold-DbContext "The method or operation is not implemented"
玩得不开心。
PM> 命令 运行
Scaffold-DbContext "Server=myserver;Database=mysqlserverdb;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -Tables Settings -verbose
错误：
The method or operation is not implemented.
System.NotImplementedException: The method or operation is not implemented.

在 Microsoft.EntityFrameworkCore.Design.OperationExecutor.OperationBase.Execute（动作动作）`
在安装 EF power Tools 和 Latest Core 2.2.x.x SDK 之间，我现在可以更改我的项目使用下拉更改为 .net 核心 2.2（以前只能做 2.1。
然后通过 Nuget 更新等...，终于成功了！
