Caliburn.Micro is a small, powerful MVVM framework for building applications across all XAML platforms including WPF, UWP, WinUI3, Avalonia UI, .NET MAUI, and Xamarin.Forms. It provides convention-based view-model binding, actions with guard methods, screen conductors, and an event aggregator to enable rapid, testable UI development.

Use cases

• build a WPF desktop app with MVVM
• bind view models to XAML views by convention
• share UI logic across WPF, MAUI, and Avalonia apps
• decouple view models with an event aggregator
• implement screen and conductor composition patterns
• make XAML app logic testable without code-behind

When to choose

• you are building a .NET XAML application (WPF, UWP, WinUI3, MAUI, Avalonia, or Xamarin.Forms) and want an opinionated, lightweight MVVM framework
• you want convention-based binding to reduce boilerplate wiring between views and view models
• you need built-in composition patterns (screens, conductors) and event aggregation
• testability of presentation logic is a priority

When to avoid

• you prefer explicit data-binding with commands and no magic conventions
• you are building a web or non-XAML UI
• you want a framework with a large ecosystem and extensive third-party tooling
• you need a minimal, unopinionated MVVM library without conventions
