GenerateDocumentationFile is a .NET project setting that makes the compiler create an XML documentation file whenever the project builds. section 11.2.3
In the project file, add the setting inside a PropertyGroup. Public types and members without three-slash comments then raise CS1591 warnings. section 11.2.3
Choose how the project handles missing documentation:
- Keep CS1591 enabled to identify public APIs that still need documentation. section 11.2.3
To expose the generated content in Swagger UI, configure Swashbuckle to locate the XML file. Reflection derives the project filename, avoiding a hard-coded name. section 11.2.3
Verify the generated documentation
Build and run the API in Debug mode, then inspect Swagger UI. Documented endpoint summaries, parameters, and return descriptions should appear in the interface. section 11.2.3
