Linux 系统搭建 .NET 环境

下载安装

巨硬官网 - https://dotnet.microsoft.com/zh-cn/download/dotnet
环境很简单，根据需要选择版本；SDK 很大，如果不需要在 Linux 上开发，只需要安装运行时即可

rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm
yum update
yum -y install dotnet-runtime-3.1
yum -y install dotnet-sdk-3.1
yum -y install aspnetcore-runtime-3.1

版本区分

注意：aspnetcore 和 dotnet 是两个东西
/usr/share/dotnet/shared/Microsoft.NETCore.App/3.1.23

dotnet --info
