## What it is
WiX Toolset v3 builds Windows Installer (MSI) packages and executable bundles from XML source code via a command-line environment. It integrates into build processes and is Microsoft's first open-source project, though v3 is now out of community support.

## Use cases
- build msi installers from xml source
- create windows installer packages in ci build pipeline
- generate executable bundles for windows deployment
- integrate installer creation into automated builds
- version-control installer source as xml text files

## When to choose
- you need full control over Windows Installer MSI packages
- you maintain legacy projects already using WiX v3
- you want text-based installer sources that work with source control

## When to avoid
- starting a new project — use WiX v4/v5 or newer instead
- you need community support, which v3 no longer receives
- you need cross-platform installers for non-Windows targets

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: build-tool, developer-tools
- domain: developer-tools, windows
- platform: windows, cli, dotnet
- tags: installer, msi, windows-installer, xml, packaging, deployment
