Windows App SDK 和传统 Windows SDK 有什么区别
Windows App SDK支持跨不同平台（如Win32、.NET）而使用统一API，而Windows SDK更偏向底层系统接口。
Windows App SDK：支持WinUI 3，提供更高级别的开发接口，开源
运行时依赖：需要部署Windows App SDK Runtime（1.0.0+），而Windows SDK功能内置于操作系统
使用： Windows App SDK为Visual Studio 2022提供了扩展。Windows App SDK库可通过NuGet包获得以便安装在现有项目中。
安装tools：打开cmd winget install “Visual Studio Professional 2022” –override “–add Microsoft.VisualStudio.Workload.NativeDesktop Microsoft.VisualStudio.ComponentGroup.WindowsAppSDK.Cpp” 确保安装了 Windows App SDK C++ Templates
