I’d agree that Avalonia has come a long way in a short time. It has a lot of potential, but there aren’t a lot of UI control libraries available yet.
I’m using it for a personal project and it’s very good for cross platform consistency. The trouble is that building a good looking UI is still difficult. Some of that is my lack of knowledge, but some is lack of available docs, examples, and community.
Here’s hoping they keep growing those things and become a viable alternative.
That would be my dream.
