Windows Input and Composition sample


We've switched over the sample project to consume from the Windows App SDK. For the Universal Windows Platform version of the Windows Composition Samples, please visit this release.

Windows Input and Composition Samples

Welcome to the Windows App SDK Input and Composition Samples! For those of you familiar with the Windows Composition Samples, these samples are very similar but instead built on the APIs in the WinAppSDK (to learn more about the WinAppSDK, visit here), and they also feature new input APIs. This is the place for the latest code samples, demos, and developer feedback around building beautiful and engaging WinUI3 apps. This repo focuses on the platform building blocks that make up the Fluent Design System, with emphasis on creating UI using APIs in the Microsoft.UI.Composition and Microsoft.UI.Input namespaces.

Inside this repo, you’ll find the following additional info:

If you are a developer getting familiar with the WinUI 3.0 platform, want to build beautiful and innovative UI experiences, and don't mind a few bugs here and there, then this is the place for you!

We also want to see what inspiring UX you're building, so feel free to reach out on Twitter @WindowsUI.

Project Structure

The following outlines the key folders for the project.


The Demos folder contains standalone code demos that are focused on combining many concepts and feature sets into interesting user experiences.

Sample Gallery

The Sample Gallery is an application that contains many samples, each demonstrating a different concept or API. The WinAppSDK samples automatically work downlevel to Windows 10 version 1809 (build 17763) which means as long as your Windows OS version is 1809 or higher, you'll automatically get all the latest features.

Samples Common

These are early reference implementations, prototypes, and utilities the team has built over the course of developing our demos and code examples. This is a set of common code patterns that are shared across code samples and demos.


A set of C# classes enabling you to build ExpressionAnimations in a more type-safe environment.

Samples Native

A native library used to access some lower-level functionality that has no WinRT projections.


We encourage and welcome community involvement and contribution in this project. You'll find some details and guidelines for contribution in the contributing readme.
