Ports and Adapters (Hexagonal) Architecture in C#
Introduced by Alistair Cockburn in 2005, the Ports and Adapters architecture, also known as the Hexagonal Architectural Pattern, remains relevant today. This approach emphasizes loose coupling between application components, making them easier to test and maintain. By separating the core logic from external systems, it allows applications to interact with various sources (users, programs, tests) independently. Changes in external systems impact only the adapters, leaving the core logic untouched.
