Sandcastle
Sandcastle is a robust .NET documentation generator designed primarily for creating API documentation for .NET Framework libraries and frameworks. It processes XML documentation files generated by the C# compiler to produce comprehensive HTML-based help files, which can include API references, conceptual topics, and other essential documentation elements. With a variety of customization options, Sandcastle allows users to control the appearance and structure of the generated documentation, making it adaptable to diverse project needs. It integrates seamlessly with Visual Studio, enhancing the workflow for .NET developers. While Sandcastle has a dedicated community that offers support and resources, users may encounter a learning curve, particularly if they are new to documentation generation or its configuration. Additionally, it relies on XML documentation comments, necessitating adherence to specific formatting. Although primarily focused on .NET Framework projects, Sandcastle remains a mature and well-established tool for generating comprehensive and customizable documentation.
