Indeed, if you attempt to look for modern windows/mac UI development tools it's either Visual Studio/C# or nothing. It's like development in that direction has ceased. Modern languages require complex tooling to get from zero to a UI, IE Rust/Go/Python, etc.

Rider supports AvaloniaUI and Uno. And both also ship extensions for Visual Studio Code.

You are not tied to Visual Studio or Windows (as in, you can target Windows and Linux when using macOS, or Windows and macOS when using Linux).

Rust is generally anemic if you need a visual editor. Go and Python are in even worse state (there are no production-ready frameworks for Go to do cross-plat GUI app dev).

The biggest alternative so far is Flutter.
