Hello everyone, I'm Wolf at the End of the Desert.
Just hanging out in a WeChat group, a netizen shared an Uno online mini-game. The site owner thought it was pretty cool, so here's a quick share:

What is Uno?
An open-source UI platform for building pixel-perfect multi-platform applications using C# and WinUI, enabling single-codebase apps for Windows, iOS, Android, WebAssembly, macOS, and Linux.

Since it's developed using Web Assembly, despite the promise of "fast, efficient, and portable—by leveraging common hardware capabilities, WebAssembly code can run at near-native speed across different platforms," Uno also brings its runtime, so the site size is a bit large—about 28MB, taking around 10 seconds to load. It's recommended to use a scientific tool if you want to play.
Simple introduction to Web Assembly: A binary format for the web. WebAssembly (wasm) is a virtual instruction set architecture (virtual ISA). Its overall architecture includes the core ISA definition, binary encoding, definition and execution of program semantics, and an application programming interface (WebAssembly API) for different embedding environments (such as the web). Its initial goal is to allow programs written in languages like C/C++ to be compiled and run on the Web platform with better security and near-native application speed. — Excerpt from Baidu Baike

Due to varying network environments, the site size is a bit large, so there's a loading page to avoid boring waits:

Judging from the latest code commits, this framework is very active and a strong competitor to MAUI. If you're interested, go check it out.
