## What it is
WPF UI is a C# library that brings Fluent Design (Windows 11 style) to Windows Presentation Foundation applications, restyling base controls and adding controls like Navigation, NumberBox, Dialog, and Snackbar. It is distributed via NuGet and includes a Visual Studio 2022 extension and a Gallery app for exploring its controls.

## Use cases
- give my WPF app a modern Windows 11 Fluent look
- add dark and light themes to a WPF application
- find Fluent-style WPF controls like NavigationView and Snackbar
- modernize a legacy WPF desktop application's UI
- implement Mica backdrop in a WPF window
- create a new WPF project with MVVM and dependency injection preconfigured

## When to choose
- you are building or modernizing a WPF desktop app on Windows and want native Fluent design
- you want a free, MIT-licensed alternative to paid UI suites with active development
- you work in Visual Studio 2022 and want designer-compatible XAML styles out of the box

## When to avoid
- you target platforms other than Windows, since WPF is Windows-only
- you use WinUI 3, Avalonia, or MAUI instead of WPF
- you need cross-platform .NET UI

## Facets
- artifact type: library
- maturity: active
- function: ui-components, theme, frontend-framework
- domain: desktop-applications, web-design, cross-platform
- platform: windows, dotnet
- tags: wpf, fluent-design, xaml, csharp, windows-11, mica, mvvm, nuget, desktop
