## What it is
Microsoft's cross-platform MSIX SDK for packing and unpacking .msix/.appx application packages on Windows, macOS, Linux, and Android. It provides a shared library, a makemsix CLI tool, and MSIX Core for installing packages on older Windows versions.

## Use cases
- pack an app as an msix package on linux
- unpack appx package contents cross-platform
- install msix packages on windows 7
- build a tool that reads msix package manifests
- distribute app packages via own CDN
- programmatically create appx bundles

## When to choose
- you need to pack or unpack .msix/.appx packages outside the Windows SDK
- you want to install MSIX packages on Windows 7 SP1+
- you're building cross-platform tooling around MSIX package format

## When to avoid
- you only target modern Windows 10/11 where the built-in AppX APIs suffice
- you need full MSIX feature parity with the Windows packaging APIs

## Facets
- artifact type: library
- maturity: active
- function: compression, file-system, cli, sdk
- domain: developer-tools, windows, cross-platform, files
- platform: windows, cpp, c
- tags: msix, appx, packaging, uwp, app-distribution, linux, macos, android
