Structuring ASP.NET Core Web API controllers involves applying specific design patterns for clarity and separation of concerns. This ensures your API endpoints remain maintainable and scalable as the project evolves.

The best way to handle model binding and validation in ASP.NET Core is using built-in mechanisms to process incoming data. This ensures only valid data reaches controller logic, preventing common API errors.

Implementing API versioning and error handling in ASP.NET Core requires applying specific patterns to manage API evolution. This delivers consistent error responses across endpoints while maintaining backward compatibility.

You can use this approach to refactor an existing ASP.NET Core Web API to improve its structure, validation, and error handling. It helps align legacy codebases with modern .NET conventions without requiring a complete rewrite.

This guidance specifically covers building controller-based ASP.NET Core Web APIs. It focuses on traditional controller structure, routing, and model binding rather than the newer minimal API approach.
