Svelonia

A C# UI framework for Avalonia built with a focus on developer experience, fine-grained reactivity, and fluent APIs. Inspired by Svelte and SolidJS.

Features

• Fine-Grained Reactivity: Accurate updates without a Virtual DOM or full re-renders.
• Fluent UI: Build interfaces entirely in C# with a chainable, type-safe API.
• File-based Routing: Automatic route discovery and parameter injection.
• Clean Architecture: Built-in Mediator pattern and DI support.
• AOT Ready: Optimized for Native AOT.
