## What it is
A collection of Microsoft's Windows Input and Composition samples demonstrating Fluent Design UI using Microsoft.UI.Composition and Microsoft.UI.Input APIs, including demos, a sample gallery app, and reference utilities. The repo has moved into the WindowsAppSDK-Samples repository and is now read-only.

## Use cases
- learn Windows Composition APIs for building animated UI
- find WinUI 3 code samples for Fluent Design effects
- see examples of input and interaction APIs in Windows App SDK
- build beautiful engaging desktop app experiences on Windows 10+
- study reference implementations of composition-based UI patterns

## When to choose
- you are learning WinUI 3 or the Windows App SDK composition and input APIs
- you want working C# examples of Fluent Design animations and effects
- you need a sample gallery app to explore composition concepts on Windows 10 1809+

## When to avoid
- you need a production-ready UI library rather than sample code
- you target platforms other than Windows
- you expect active development here - the samples moved to WindowsAppSDK-Samples/SceneGraph
- you need UWP-era samples without checking the UniversalWindowsPlatform release branch
