ASP.NET Core — API and Presentation Layer

In enterprise .NET Core architectures, ASP.NET Core typically acts as the presentation layer.

Key responsibilities:

1. HTTP endpoints — controllers or minimal APIs.

2. Model binding and validation.

3. Authentication and authorization.

4. Mapping between DTOs and application commands/queries.

Architecture rule: Controllers should be thin — they delegate to the application layer, not contain business logic.
