Someone ported VLC 3’s UI to Avalonia on Windows, macOS, and Linux in just 16 working days (290 commits). Absolute madness. 🤯 Got an Avalonia Port Challenge entry of your own? You have until this Friday, Oct 23 at 23:59 UTC! Reminder: The write-up is scored, so don’t forget to document what broke along the way.

Avalonia gives you control over every pixel of your UI, which means a cross-platform app can look indistinguishable from the native toolkit (if you want it to). This is a 100% Avalonia app.
