Answer
Use Swagger / OpenAPI:
- Interactive documentation
- Multiple version support
- Authentication integration
- Schema validation
Quick Answer
API documentation with Swagger: install Swashbuckle.AspNetCore. AddSwaggerGen() in services, UseSwagger() and UseSwaggerUI() in middleware. Add XML comments: tags and [ProducesResponseType] attributes generate rich docs. Configure JWT auth in Swagger UI for testing protected endpoints. Generate OpenAPI spec for client code generation. Keep docs in sync - use contract-first approach.
