We're excited to announce our newest challenge with Uno Platform!

Running through December 7, the AI Challenge for Cross-Platform Apps invites you to build native cross-platform apps from a single shared codebase using .NET and Uno Platform's AI-powered tools.

Whether you're exploring Uno Platform for the first time or leveling up your .NET skills, this challenge is the perfect opportunity to explore building apps that run everywhere: iOS, Android, Windows, macOS, Linux, and WebAssembly - all from one codebase.

We hope you give it a try!

Our Prompts

WOW Factor

Build something visually stunning and fun — fast. Create a coffee shop–style home screen (or any theme you like) that runs across iOS, Android, Windows, macOS, Linux, and WebAssembly — all from a single Uno Platform codebase.

What to do:

Start your project manually or kick it off using App MCP or Hot Design Agent for AI-assisted setup
