Caliburn.Light

A magic-free MVVM framework for building modern .NET applications with WPF, WinUI 3, and Avalonia.

Features

• Magic-free — no conventions, no surprises; explicit configuration only
• Screens & Conductors — lifecycle management with activation, deactivation, and close guards
• Commands — type-safe DelegateCommand and AsyncCommand with builder pattern
• Event Aggregator — loosely-coupled pub/sub messaging with weak references
• Validation — built-in INotifyDataErrorInfo support with rule-based validation
• Window Manager — show windows, dialogs, and file pickers in a ViewModel-centric way
• Weak Events — memory-efficient event handling to prevent leaks

Inspired by Caliburn.Micro, Prism, and MVVMLight.
