UI in code
Fluent extensions named after the properties, ready panels, events to named methods, styles in code.
MIT · .NET 10 · Avalonia 12 · v2.10.2
Avalonia user interfaces written in C#, without XAML.
RAVAL is the in-house library of Arato Ingegneria for lab and bench software: fluent extensions to build windows in code, hand-drawn charts (curves, Smith chart, polar, bars, maps), tables of a hundred thousand rows, trees, one-line dialogs, colored log, settings, theme and languages. Free, MIT licensed.
A window in ten lines
No XAML, no bindings to guess, no lambdas: controls are built with extensions named after their properties, events go to named methods, and what you read is what happens.
