Uno Platform Studio 3.0 was announced at Microsoft Build, introducing a browser-based AI-powered development environment for building cross-platform .NET apps. Developers can start from a text prompt in the browser with no local installation required — an AI agent scaffolds a full .NET project using XAML and C#, with live hot-reload previews as code is generated. The environment supports design tools, responsive previews, light/dark mode switching, and manual UI editing. Once satisfied, developers export a standard Uno Platform project zip and continue locally in VS Code, Visual Studio, or Rider. MCP (Model Context Protocol) servers and Uno-specific AI skills are available both in-browser and locally to ground AI agents in framework documentation and best practices.
