Markdig

A fast, powerful, CommonMark compliant, extensible Markdown processor for .NET. Very fast parser and HTML renderer (no-regexp), very lightweight in terms of GC pressure. Abstract Syntax Tree with precise source code location for syntax tree, useful when building a Markdown editor. Check out MarkdownEditor for Visual Studio powered by Markdig!

Parses trivia (whitespace, newlines and other characters) to support lossless parse ⭢ render roundtrip. This enables changing markdown documents without introducing undesired trivia changes. Special attributes or attached HTML attributes (inspired from PHP Markdown Extra - Special Attributes). Diagrams extension whenever a fenced code block contains a special keyword, it will be converted to a div block with the content as-is.
