WinMD API Search

This skill helps you find the right Windows API for any capability and get its full details. It searches a local cache of all WinMD metadata from:

- Windows Platform SDK - all Windows.* WinRT APIs (always available, no restore needed)

- WinAppSDK / WinUI - bundled as a baseline in the cache generator (always available, no restore needed)

- NuGet packages - any additional packages in restored projects that contain .winmd files

- Project-output WinMD - class libraries (C++/WinRT, C#) that produce .winmd as build output

Even on a fresh clone with no restore or build, you still get full Platform SDK + WinAppSDK coverage.

When to Use This Skill

- User wants to build a feature and you need to find which API provides that capability

- User asks "how do I do X?" where X involves a platform feature (camera, files, notifications, sensors, AI, etc.)

- You need the exact methods, properties, events, or enumeration values of a type before writing code

- You're unsure which control, class, or interface to use for a UI or system task
