## What it is
A fast, cross-platform multipart downloader library for .NET applications with asynchronous progress events. It supports parallel chunked downloads, pause/resume, and works across .NET Standard, .NET Framework, and modern .NET runtimes.

## Use cases
- download large files with multiple parallel connections in a .NET app
- add a download manager with progress events to my C# application
- resume interrupted downloads programmatically
- build a cross-platform file downloader on .NET
- limit download speed and manage concurrent downloads
- replace Internet Download Manager functionality inside my app

## When to choose
- you need a reliable, embeddable download engine in a .NET project
- you want multipart/parallel downloads with async progress reporting
- you need cross-platform support across Windows, Linux, and macOS

## When to avoid
- you need a ready-made GUI download manager rather than a library
- your project is not on the .NET platform
- you only need simple single-stream downloads with no progress tracking

## Facets
- artifact type: library
- maturity: active
- function: http-client, file-system, concurrency
- domain: developer-tools, cross-platform, files
- platform: dotnet, cross-platform, windows
- tags: download-manager, multipart-download, async, nuget, csharp, linux, macos
