Mediator Pattern – centralized communication between components

Mediator Pattern is a behavioral design pattern that enables communication between components through a central object (mediator), reducing direct dependencies and increasing architectural clarity. In this article, you will see how the Mediator Pattern can be applied in a .NET (C#) application, including practical examples and real scenarios from modern applications (UI, business logic, DDD).

Chain of Responsibility – processing flows in chain

The Chain of Responsibility pattern allows processing a request through a chain of handlers, each having the chance to handle it or delegate it further. It is ideal for validations, pipelines, sequential processing, and flexible systems where the logic can be extended without affecting the existing code.
