Summary
This is the canonical workflow for WinUI 3 development in Claude. It bundles project scaffolding, a BuildAndRun.ps1 script that handles platform detection and launch mechanics, and a comprehensive error reference for the most common build and runtime failures. The big win is that it enforces async invocation for long-running processes and uses winapp run instead of letting you launch the exe directly, which silently breaks packaged apps. If you're building WinUI 3 apps or diagnosing why they won't compile or crash on launch, this should be your first stop. The prerequisite matrix and error table alone will save you from chasing outdated Stack Overflow answers.
