Use Uno Platform instead of AvaloniaUI

Uno is easier to work with and more feature rich in my experience

Is Uno really that better? Avalonia is pretty close to wpf (Windows Lively) in development process.

What about performance, memory usage etc?

The online Uno demo is not smooth: https://gallery.platform.uno/

Uno isn't great with WebAssembly, but it's really smooth on bare-metal. I've checked out Avalonia again and it seems they've added a lot of missing features that I was annoyed about. One great thing that I've discovered that Avalonia supports Fluent effects on Linux, so Lively looks top notch! As for performance, they're both about the same.

That looks real nice. I noticed the memory consumption also reduced (in Windows) in the new version.
