Frequently Asked Questions

FAQPage Schema

How to install microsoft-ui-reactor?▼

Run `npx skills add microsoft/microsoft-ui-reactor --all -g -y` in your terminal to install all skills in this suite globally.

What is Microsoft.UI.Reactor?▼

It is a declarative, component-based C# framework for building WinUI 3 desktop apps, using a React-style model with hooks and a reconciler instead of XAML and ViewModels.

Can AI agents build Windows desktop apps with these skills?▼

Yes. The skills teach agents the full Reactor workflow, from scaffolding an app and writing components to running builds, fixing diagnostics, and driving a running app via devtools.

Do I need to know XAML to use Reactor?▼

No. Reactor replaces XAML with typed C# factory methods and fluent modifiers, so everything is plain C# with full IntelliSense and compile-time checking.

What kinds of UI can these skills help build?▼

They cover forms with validation, multi-page navigation, charts and data visualization, docking IDE-style layouts, windowing, gestures, theming, and accessibility.
