Built for professional Avalonia development.
When Avalonia becomes part of your daily workflow, upgrade to a paid subscription and unlock the most productive features. As your applications grow, so does the complexity of your XAML. The Plus edition doesn't just edit your code, it understands it. By analysing your XAML, it catches issues the compiler misses, automates repetitive refactorings, and gives you powerful tools for navigating and maintaining growing applications. It's included with every Avalonia Plus, Pro and Enterprise subscription.

Why upgrade
Professionals invest in tools that save them time.
The Community edition is an excellent way to start building with Avalonia. The Plus edition is designed for developers who build with Avalonia every day, where every interruption, every manual refactoring and every avoidable bug slows development. Plus removes that friction, so you can stay focused on building your application.
Your views no longer fit in your head
Files run to hundreds of lines and finding one control means scrolling. The outline keeps the whole tree in view beside the editor.
The compiler says everything is fine. Your users disagree.
Grid coordinates that point nowhere compile without complaint. The advanced analysis available in the Plus edition immediately flags them.
The same properties are pasted across controls
Copied inline styling drifts apart quietly. One-click refactorings pull them into shared styles you maintain in a single place.
You're building from memory instead of intent.
The toolbox puts every control a drag away, so you build from what you can see rather than what you can remember.
Editions
Avalonia for VS Code comes in two editions
Community provides core XAML editing capabilities at no cost, while Plus unlocks the full power of the extension with deeper refactoring and productivity features.
