visual studio 2019从mysql数据库表通过命令自动生成实体类模型
一、通过Nuget 安装依赖包，命令如下：
Install-package mysql.data.entity -Version 6.8.8
Install-package mysql.data -Version 6.10.9
Install-package mysqlConnector -Version 0.68.0
install-package pomelo.entityFrameWorkCore.mysql
install-package Microsoft.EntityFrameworkCore
install-package Microsoft.EntityFrameworkCore.Tool
二、 Scaffold-DbContext "Server=MysqlServerIP;Database=MysqlDatabaseName;UserID=YourMysqlUserID;Password=YourMysqlUserPassword;port=3306;Charset=utf8;pooling=true;Allow User Variables=True;" Pomelo.EntityFrameworkCore.MySql -OutputDir YourOutputdirPath -tables YourTableName
最后，强调一点，这个windows下测试成功的，命令不区分大小写，linux下面是区分大小写的。最重要的是版本冲突的解决。附上所有测试依赖包（get-package）：
