WinUI Community Toolkit (C++ Port)

This repository contains C++ ports of CommunityToolkit components.

The goal is to allow seamless usage of these controls in WinUI 3 / C++ projects.

EffectAnimations (XamlToolkit.WinUI.Media.Animations)

---

XamlToolkit.WinUI.Interactivity

A C++/WinRT port of XamlBehaviors, providing a lightweight behavior and trigger system for WinUI 3 applications.

This module ports the original C# WinUI XamlBehaviors implementation to C++/WinRT, while keeping full API compatibility for seamless migration.

Notes

• ChangePropertyAction and CallMethodAction are not implemented (due to lack of reflection support in C++/WinRT); instead, property mutation is split into:

  • ChangeCustomPropertyAction
  • ChangeDependencyPropertyAction

• DataTriggerBehavior may not work with certain types.

• EventTriggerBehavior includes default event mappings; missing events must be manually registered via EventManager.

XamlToolkit.WinUI.Behaviors

Features

• Native C++/WinRT implementation for WinUI 3.
• API style compatible with CommunityToolkit controls.

Build Steps

• Requires Visual Studio 2026 or later for compilation.
• To build XamlToolkit.Labs.WinUI, you need to install tree-sitter via vcpkg:

vcpkg install tree-sitter:x64-windows-static

Markdown parsing uses md4c (https://github.com/mity/md4c).
Since vcpkg does not support configuring UTF-16 character set for md4c, the project directly includes the md4c source code.

Usage

NuGet

Add nuget packages to your project.

Add an XML namespace like this in your XAML

xmlns:ui="using:XamlToolkit.WinUI"
xmlns:controls="using:XamlToolkit.WinUI.Controls"
xmlns:convertors="using:XamlToolkit.WinUI.Convertors"
xmlns:labs="using:XamlToolkit.Labs.WinUI"
xmlns:media="using:XamlToolkit.WinUI.Media"
