The choice between using controllers or minimal APIs in ASP.NET Core depends on the specific needs and requirements of your application. Both approaches have their advantages and disadvantages.
Controllers are a traditional approach to building APIs in ASP.NET Core. They provide a clear separation between the API endpoint, the business logic, and the data access layers of an application. Controllers allow developers to easily organize their code and make it more modular, making it easier to maintain and test.
Minimal APIs are a newer approach to building APIs in ASP.NET Core. They provide a simpler and more lightweight way to build APIs. Minimal APIs are typically used for smaller, less complex APIs, where there is less need for separation of concerns and more emphasis on simplicity and speed of development.
In general, if your application is complex and requires a lot of business logic or data access, using controllers is likely the better option. If your application is smaller and requires less complexity, then using minimal APIs might be a better choice.
Ultimately, the choice between using controllers or minimal APIs should be based on the specific requirements and constraints of your application, as well as the experience and preferences of your development team.
