## What it is
Source Link is a set of .NET build tools and NuGet packages that embed source control metadata into binaries, symbols (PDBs), and packages so debuggers can download the exact commit-specific source code. It is language- and source-control agnostic and is included by default in the .NET 8+ SDK for GitHub, Azure DevOps, GitLab, and Bitbucket.

## Use cases
- enable source stepping into NuGet package dependencies in Visual Studio
- embed source control metadata in PDBs and assemblies
- publish debuggable .NET libraries with source linking
- debug third-party .NET packages at the exact commit
- set up source debugging for private GitHub or Azure DevOps repos

## When to choose
- you publish NuGet libraries and want users to debug into your source
- you want breakpoints and source stepping in arbitrary .NET dependencies
- you need commit-specific source downloads during debugging

## When to avoid
- your project is not on .NET or a supported source control host
- you cannot distribute PDBs or source URLs publicly
- you only need local debugging of your own code without package distribution

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, build-tool
- domain: developer-tools, version-control, testing
- platform: dotnet, cross-platform, windows
- tags: source-link, debugging, pdb-symbols, nuget, source-control-metadata, csharp, debugging-metadata, linux, macos
