About this tag
The Windows App SDK is Microsoft's modern development framework for building native Windows 11 applications, often paired with WinUI 3. Recent discussions focus on its role in enabling local AI features, such as running Phi Silica language models on non-Copilot+ PCs with NVIDIA RTX GPUs. Microsoft has recommitted to the SDK at Build 2026, adding AI-assisted tooling and command-line templates. Performance improvements for WinUI 3 apps, including smoother resizing and better File Explorer benchmarks, are also highlighted. The SDK is central to Microsoft's strategy to revitalize native Windows development and move away from web-based UI components.
