1、在系统的中断命令行中输入如下命令，安装.NET 8环境。
wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo apt-get install -y apt-transport-https
sudo apt-get update
sudo apt-get install -y dotnet-sdk-8.02、在终端命令行中使用dotnet --version 查看安装的.NET 版本。如下图。
3、下载安装Rider，现在针对个人免费喽。下载后解压在bin目录下双击 rider.sh 可执行程序，运行rider。
4、安装Uno Platform 。
dotnet tool install -g uno.check
dotnet tool update -g uno.check
uno-check5、在Rider中添加Uno Platform的项目模版。在欢迎页面选择左下角的设置->插件->搜索Uno Platform->安装->重启IDE，重启IDE后再新建解决方案中就可以找到Uno Platform的项目模版了。
6、创建项目后运行效果如下图。
7、上文中没有关于android环境的配置，接下来补全。如果选择了包括android和ios等系统，会发现如下错误提示。
