Just a record, just a Hello World experience, don't expect too much.
1. Introduction
After a few hours of tinkering, the MAUI environment is finally set up. Here's a screenshot of Hello World:
1.1 MAUI on Windows

1.2 MAUI on Android

2. Saw a group chat push this morning
Click the link to view the push: iQIYI Preview Listed on Microsoft Win11 Store: New WinUI 3 Version, Software Interface Overhaul (with Download Link)

Is the WinUI 3 used by iQIYI different from the WinUI used in MAUI Windows development? If you know, please leave a comment to clarify:

3. Introduction Before MAUI Environment Installation
MAUI-Check: This is a detection tool for installing MAUI. Some issues may arise during the installation process.
Here is the installation process:

The following exception may occur:

Don't worry; here is the installation guide article (not translating it, too tiring). As long as you have a scientific internet tool, try a few more times, and you might succeed, haha.
3. Formally Installing the MAUI Environment
Mac

The site admin got stuck on the workload installation failure, multiple attempts unsuccessful. Giving up on Mac for now, will study later.

Windows
The site admin mainly followed this link to set up the environment, succeeded after a few hours of tinkering.
4. Conclusion
If the above links don't work, you can also search Google for other articles. There are many installation tutorials online. It's best to use Google and watch YouTube videos.
Yesterday and today were just for experiencing the MAUI development experience. Hot reload is very fast, and MAUI has great potential. Personally, the site admin might use MAUI for desktop applications (and mobile apps too), but for now, I won't study MAUI further; I'll revisit it later this year or next year.
This post is just a report on the MAUI Hello World experience. That's it.
