## What it is
CsQuery is a C# jQuery port for .NET 4 that provides a complete CSS2/CSS3 selector engine, a standards-compliant HTML parser, and jQuery-style DOM manipulation methods. It indexes documents for fast selector evaluation and is intended for server-side HTML processing.

## Use cases
- parse and manipulate html in c#
- scrape web pages with css selectors
- post-process html before serving
- query html dom with jquery-style api
- parse invalid html into a standards-compliant dom

## When to choose
- you need jQuery-like CSS selector querying in .NET 4
- you want a Gecko-identical HTML parser for messy markup
- you need fast indexed CSS selector evaluation on the server

## When to avoid
- you need an actively maintained library - the author recommends AngleSharp instead
- you are on modern .NET versions beyond .NET 4
- you need bug fixes or support for known issues

## Facets
- artifact type: library

- function: parser, web-scraping, search-engine
- domain: web-development, parsers, developer-tools
- platform: dotnet
