+
+Avalonia官方参考文档：https://docs.avaloniaui.net/docs/next/guides/platforms/rpi/running-on-raspbian-lite-via-drm
+
+1.Linux端运行命令
+ sudo apt update
+ sudo apt upgrade
+ sudo reboot
+ sudo apt - get install libgbm1 libgl1 - mesa - dri libegl1 - mesa libinput10
+
+2.安装测试工具测试(出现一个彩色立方体说明环境安装完成)
+ sudo apt-get install kmscube
+ sudo kmscube
+
+3.安装.net运行时(参考网址：https://learn.microsoft.com/zh-cn/dotnet/core/install/linux?WT.mc_id=dotnet-35129-website)
+
+4.新建一个Avalonia项目，nuget里面添加Avalonia.LinuxFramebuffer包
+
+5.添加StartLinuxDrm代码(不知道怎么添加看Semi.Avalonia.Demo.Drm项目代码)
+
+6.发布程序到Linux(安装.net，怎么运行这些省略)
+            
+7.运行 ./Semi.Avalonia.Demo.Drm --drm
