https://www.yuque.com/yuejiangliu/dotnet/ggh9yb

需要三个包：

dotnet add package Microsoft.EntityFrameworkCore.Design

dotnet add package Pomelo.EntityFrameworkCore.Mysql

 dotnet add package Microsoft.EntityFrameworkCore.Tools.DotNet

打开项目文件，在 <ItemGroup /> 中添加一个 <DotNetCliToolReference />：（注意版本号）

<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.3" />

dotnet ef dbcontext scaffold

 "Server=localhost;Database=sakila;Uid=YourUserName;Pwd=YourUserPassword;SslMode=none"

"Pomelo.EntityFrameworkCore.MySql" -d -f -o Models

dotnet ef dbcontext scaffold

"Server=192.168.7.11;Database=巴食川珍;uid=sa;pwd=qingqing;"

"Microsoft.EntityFrameworkCore.SqlServer" -d -f -o Models

链接字符串：mysql：Server=localhost;Database=sakila;Uid=YourUserName;Pwd=YourUserPassword;SslMode=none

sqlserver：DataSource=LocalHost;Database=sakila;Uid=YourUserName;Pwd=YourUserPassword;
