## What it is
SteamKit2 is a .NET library for interoperating with Valve's Steam network protocol. It provides a simple, extensible interface for performing actions on the Steam network programmatically.

## Use cases
- interact with the Steam network from .NET
- log in to Steam programmatically
- send and receive Steam network messages
- build Steam bots or automation tools
- query Steam user and game data
- reverse-engineer Steam protocol interactions

## When to choose
- you need a .NET library to communicate with Steam's network protocol
- you're building bots, tools, or services that automate Steam actions
- you want an extensible, community-maintained Steam client library

## When to avoid
- you only need official Steam Web API access rather than the network protocol
- your project is not on .NET
- you need a supported, officially sanctioned Steam API (Valve does not officially support this library)

## Facets
- artifact type: library
- maturity: active
- function: networking, sdk, serialization
- domain: gaming-tools, developer-tools, apis
- platform: dotnet, cross-platform
