UnoConf 2021 Recap: Highlights and Uno Platform 4.0 Launch 🚀

This year’s UnoConf reminded me why I’ve been so excited about following Uno Platform since the beginning. Even though we couldn’t all be in the same room yet, the event brought together viewers from over 30 countries — proof that Uno is resonating with developers all over the world.

The biggest news? Uno Platform 4.0 was officially launched during the keynote! 🎉

Uno Platform 4.0 Release ✨

Version 4.0 is a huge milestone. It runs on top of the newly released .NET 6 and supports WinAppSDK 1.0 (including WinUI 3). From day one, Uno Platform aimed to be more than just a UI framework — it wanted to be a true platform, and this release shows just how far that vision has come.

Here are some of the new additions we saw at the conference:

• Uno Extensions → Productivity helpers for new projects. Includes App Templates (patterns + recipes with DI, logging, serialization) and Uno Reactive (MVUX) for reactive, declarative business code in XAML.

• Uno Toolkit → Eleven new controls built for a multi-platform world. Highlights included the Tab Bar (top and bottom formats), Navigation Bar, and a surprise Auto Layout control. More controls are on the way, supporting both Cupertino and Material designs.

• VS Code Extension → A preview that brings C# and XAML IntelliSense into VS Code, plus Hot Reload for faster iteration without restarting your app.

• Uno Platform for Figma → A free preview that lets designers work with WinUI and Material component libraries in Figma, then live-preview designs and export XAML directly into apps.

Sessions & Demos 🎤

UnoConf 2021 was packed with great sessions covering real-world scenarios and practical tips for working with Uno:

• Uno Extensions

• Styling Uno Platform Applications

• Deploying Uno Apps to Azure

• Using Native Controls in Uno Apps

• Best Practices for Testing Uno Platform Applications

• Migrating WPF Applications to Web

• How Uno Platform Ports Features from WinUI on Day 0

We also saw case studies of Uno Platform in production with companies like TradeZero, Kahua, and Strix, showing why organizations are betting on Uno for their cross-platform needs.

My Takeaway 💡

UnoConf 2021 left me feeling both inspired and optimistic. Seeing Uno Platform 4.0 arrive with so many new features was exciting, but what stood out even more was the global energy of the community.

It’s true — I miss the in-person experience of shaking hands, sharing coffee breaks, and catching up in hallways. Hopefully, by the time we meet again, we’ll be able to enjoy those moments face-to-face. But for now, I’m grateful that technology allows us to gather online and keep building momentum together.

Looking Ahead 🌟

Uno Platform continues to prove it’s more than a framework — it’s a platform built for the future of cross-platform development. With the release of 4.0, a growing toolkit, and more community contributions than ever, I can’t wait to see what 2022 will bring.

See you at the next UnoConf — hopefully in person this time! 💜
