Learn event-driven architecture in C# with runnable examples: domain events, MediatR, message brokers, and best practices. Build loosely coupled .NET systems today. Event-driven architecture in C# is one of the most effective ways to build loosely coupled systems that scale, evolve, and stay maintainable as your codebase grows. Instead of components calling each other directly, they announce that something happened, and any interested component reacts. In this tutorial you will learn what event-driven architecture is, why it matters for .NET developers, and how to implement it step by step: from native C# events, to in-process domain events with MediatR, to cross-service messaging with a message broker like RabbitMQ or Azure Service Bus. Every example is runnable on .NET 8 or later. What Is Event-Driven Architecture in C#? Event-driven architecture (EDA) is a design style where the flow of the program is determined by events : immutable facts that something happened in the past. ...
