Services in MVC
What are Services in ASP.NET Core MVC?
Services in ASP.NET Core MVC are classes that encapsulate business logic, external API interactions, or other operations that support the application but aren't directly related to HTTP request handling (which is the controller's responsibility).
In KikiWriting, services are organized under the Services directory, grouped by feature.
Services help maintain separation of concerns by:
- Moving business logic out of controllers
- Making code more testable
- Enabling reuse across different parts of the application
Services vs. Libraries
| Services | Libraries |
|---|---|
| Scoped to the application | Can be used across multiple projects |
| Registered in dependency injection | Imported as project references |
| Follow application's naming/coding conventions | May have their own conventions |
| Can be easily mocked for testing | May be harder to mock if not designed for testability |
| Can access other application services | Typically standalone with minimal dependencies |
