Avalonia

This is your go-to when building cross-platform desktop apps with Avalonia UI, the XAML framework that works everywhere from Windows and macOS to Linux, mobile, and even WebAssembly. It's organized around six focused resources covering MVVM patterns, control references, custom controls, styling and theming, reactive programming with ReactiveUI, and platform-specific implementations. The orchestration hub does something smart: it maps your actual task (building a form, fixing list performance, adding custom styling) directly to which resources you need, so you're not reading about animations when you just need to know how ComboBox works. If you're coming from WPF or need truly native looking apps without Electron, this covers the framework end to end.
