## What it is
Stylet is a lightweight ViewModel-first MVVM framework for WPF applications on .NET Framework and .NET Core/.NET 5+. Inspired by Caliburn.Micro, it emphasizes low magic, testability, and flexibility with sensible defaults.

## Use cases
- build a WPF desktop app with MVVM architecture
- structure a WPF app so ViewModels are easy to unit test
- replace Caliburn.Micro with a simpler, less magical MVVM framework
- scaffold a new .NET WPF project with dotnet new templates
- manage window/screen navigation and conductor lifecycles in WPF
- wire dependency injection into a WPF application

## When to choose
- you are building a WPF app on .NET Framework 4.5.2+ or .NET Core 3.0+/.NET 5+
- you want a small, well-documented, comprehensively tested MVVM framework
- you like Caliburn.Micro concepts but want less magic and simpler code
- you need a framework that is easy to override and customize

## When to avoid
- you are building UWP, WinUI, MAUI, or Avalonia apps instead of WPF
- you need a full application framework beyond MVVM (e.g., Prism-style modularity)
- your project targets platforms other than Windows desktop

## Facets
- artifact type: framework
- maturity: stable
- function: ui-components, state-management, dependency-audit
- domain: desktop-applications, cross-platform, developer-tools
- platform: windows, dotnet, cross-platform
- tags: mvvm, wpf, viewmodel-first, caliburn-micro-inspired, csharp, xaml
