.net 的跨平台UI框架——MAUI

原文：Introducing .NET Multi-platform App UI
github：https://github.com/dotnet/maui

• MAUI 是 Xamarin.Forms 的进化（Xamarin.Forms 已经有6年历史了）。支持Model-View-ViewModel（MVVM）和Model-View-Update (MVU)等模式编写。
• 支持Android, iOS, macOS, and Windows（github上显示，支持Linux）
• 将于今年晚些时发布预览版。目标随 .NET 6 一起正式发布（2021年11月？）。
