Controllers and Actions in ASP.NET Core
Learn how ASP.NET Core controllers and action methods receive HTTP requests, coordinate application logic and return appropriate responses.
What Controllers Do
Controllers organise request-handling endpoints in MVC and API applications. An action method represents a callable endpoint that receives input and returns a result.
Core Concepts
- Controller classes and routing conventions
- Action methods and HTTP verb attributes
- Action parameters and model binding
- Returning status codes, JSON or views
- Keeping business logic outside controllers where possible
- Validating input before calling application services
Design Guidance
Keep controllers focused on HTTP concerns: receive validated input, call the appropriate application/service layer, and translate the result into a clear HTTP response.
