How to Install / Upgrade: Uno Platform 6.6 Adds Native AOT, Vulkan Rendering, and Broader Accessibility Support

Uno Platform 6.6 adds Native AOT publishing across five target platforms, an optional Vulkan rendering backend, and automatic registration for the framework’s Model Context Protocol servers. The release also reduces XAML boilerplate, expands cross-platform WinUI API coverage, and improves accessibility and multilingual text handling.

To install or upgrade, move your project to Uno Platform 6.6 and rebuild against the updated framework packages so Native AOT publishing, the optional Vulkan backend, and automatic Model Context Protocol server registration are available. After the package update, re-run your normal multi-platform build and publish flow, turn on Vulkan only where you want that rendering path, and keep relying on the reduced XAML surface and broader WinUI APIs already exposed by the framework.

Watch for platform-specific publish settings when enabling Native AOT, treat Vulkan as optional rather than default, and confirm Model Context Protocol servers register without manual setup. Verify by publishing with Native AOT on each of the five supported targets you use, exercising Vulkan where enabled, and checking accessibility and multilingual text behavior after the upgrade.
