This project demonstrates the Ports and Adapters (Hexagonal) architecture pattern from Alistair Cockburn (2005) using .NET 7. It separates the core business logic from external systems through well-defined interfaces (ports) and adapters. This solution includes:

• CoreApplication: Implements business logic and communicates via inbound and outbound ports.
• InboundAdapter: Receives input and forwards it to the core application.
• OutboundAdapter: Handles output from the core application.
• Dependency Injection: Managed with Microsoft.Extensions.DependencyInjection.
• Unit tests: Provided with xUnit and Moq.

This structure makes the application flexible, testable, and easy to extend with new adapters or external integrations.
