This article explains how to build an automated C# code documentation generator using AWS DevOps services, leveraging DocFx to generate static HTML documentation from source code comments and Markdown files.

• DocFx generates static HTML documentation from XML comments, Swagger files, and Markdown
• AWS CodeCommit triggers AWS CodeBuild on code commits to the repository
• Lambda functions check if documentation version exists and update index pages
• Generated documentation hosted on Amazon S3 and distributed via Amazon CloudFront
• Solution includes CloudFormation templates for Windows and Linux build environments
• Buildspec files configure DocFx installation and documentation generation process
• C# projects require DocFx.json config, index.md, and toc.yml files
• Documentation automatically updates with every code check-in to main branch
• Provides cost-effective hosting with consistent structure and version history

This solution automates documentation generation for .NET projects, ensuring documentation stays current without manual updates while reducing operational overhead and errors.
