Chris Anderson demonstrates experimental React-style state management and C# first patterns for building WinUI applications.
Developers want faster iteration, clearer control flow, and tools that work well with AI assisted coding. WinUI remains the production platform for Windows apps while adapting to these needs. This session shows how emerging C# first patterns improve developer productivity, how experimental work such as Reactor informs future direction, and how these changes fit alongside the XAML based apps developers are shipping today.

React Style Development for C# and WinUI3
So, I was just catching up and watching some of the Build Videos from the other week and noticed this one here: [video which is titled "Building WinUI Apps with C# First Patterns".
In there, he talks about an experimental way of building C# WinUI Apps using a React style component flavor of development. So he has stuff like UseState and UseReducer. There is a Render method on the component that's is constantly being updated. Its basically React but for WinUI.
Here is the github project: https://github.com/microsoft/microsoft-ui-reactor
If you havent seen it, go and watch the video. He does a full demo. Its basically building UI in code i…
