Avalonia is a multi-platform windowing toolkit - somewhat like WPF - that is intended to be multi- platform. It supports XAML, lookless controls and a flexible styling system, and runs on Windows using Direct2D and other operating systems using Gtk & Cairo.

Avalonia is now in alpha. What does "alpha" mean? Well, it means that it's now at a stage where you can have a play and hopefully create simple applications. There's now a Visual Studio Extension containing project and item templates that will help you get started, and there's an initial complement of controls. There's still a lot missing, and you will find bugs, and the API will change, but this represents the first time where we've made it somewhat easy to have a play and experiment with the framework.

As mentioned above, Avalonia is still in alpha and as such there's not much documentation yet. You can take a look at the getting started page for an overview of how to get started but probably the best thing to do for now is to already know a little bit about WPF/Silverlight/UWP/XAML and ask questions in our Gitter room.

There's also a high-level architecture document that is currently a little bit out of date, and I've also started writing blog posts on Avalonia at https://grokys.github.io/.
