引入包的名称在项目根目录输入(连接Mysql的数据包)

dotnet add package Pomelo.EntityFrameworkCore.MySql --version 2.1.4

这个版本引入用不了,换个版本
dotnet add package Pomelo.EntityFrameworkCore.MySql --version 2.0.1
可以用

　　

1.创建解决方案
    dotnet new sln -n Ken.Tutorial
2.创建.NetCore项目
    dotnet new web -n Ken.Tutorial.Web
3.将项目移到解决方案中
   dotnet sln add Ken.Tutorial.Web 

C#中的jar包配置

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <Folder Include="wwwroot"/>
