Publish Your Command Palette Extension

Guide for distributing your Command Palette extension through the Microsoft Store, WinGet, or both.

When to Use This Skill

• Publishing your extension to the Microsoft Store
• Submitting your extension to WinGet for winget install discovery
• Setting up GitHub Actions to automate builds and releases
• Creating MSIX packages for Store submission
• Creating EXE installers for WinGet submission

Publishing Options

Channel	Package Format	Discovery	Auto-Updates
Microsoft Store	MSIX bundle	Store app, ms-windows-store:// link	Yes
WinGet	EXE installer	winget install, CmdPal browse	Yes (via manifest)

Recommendation: Publish to both for maximum reach. WinGet enables direct discovery from within Command Palette.
