Uno Platform 6.4 is designed to help you build faster and smarter.

It lands Day-0 support for .NET 10 and Visual Studio 2026 and provides a backbone for AI-assisted development in Uno Platform Studio 2.0.

In addition, there are tons of new improvements in 6.4. You’ll notice it immediately: the Uno Platform Status indicator that surfaces environment health inside your IDE, Skia rendering tuned for steadier, display-synced frame pacing with lower rendering overhead, Win32 windowing enhancements for polished desktop chrome, and WebView2 reliability improvements for hybrid UI.

Most importantly, Uno Platform and Uno Platform Studio now enable agentic development. In this blog we’ll address the main news on Uno Platform itself while the AI news are covered in great depth at Uno Platform Studio 2.0 announcement post.
