## What it is
MonoTorrent is a BitTorrent library for .NET implementing a wide range of BitTorrent Enhancement Proposals (BEPs), including DHT, UDP trackers, peer exchange, and protocol encryption. It provides a full-featured torrent client engine that can be embedded into .NET applications for downloading and seeding torrents.

## Use cases
- add torrent downloading to a .NET application
- embed a bittorrent engine in a desktop app
- download files over the bittorrent protocol in csharp
- create a torrent client with selective file downloading
- implement dht and udp tracker support in dotnet
- seed and share files using bittorrent in a service

## When to choose
- you need a mature, MIT-licensed BitTorrent implementation for .NET or .NET Standard
- you want broad BEP coverage including DHT, PEX, encryption, and web seeding
- you need programmatic control over torrent downloads, file prioritization, and trackers

## When to avoid
- you need a ready-made GUI torrent client rather than a library
- your project is not on the .NET platform
- you only need to parse .torrent metadata files without downloading

## Facets
- artifact type: library
- maturity: active
- function: networking, p2p, file-upload, developer-tools
- domain: networking, files, cross-platform, developer-tools
- platform: dotnet, cross-platform, c
