What problem does it solve?

This Skill provides a comprehensive guide to implementing durable messaging patterns in .NET, enabling the creation of resilient and scalable event-driven architectures.

Core Features & Use Cases

• Messaging Fundamentals: Understand message types (Command, Event, Document) and delivery guarantees (at-most-once, at-least-once, exactly-once).
• Publish/Subscribe: Implement pub/sub using Azure Service Bus Topics, RabbitMQ Fanout Exchanges, and MassTransit.
• Competing Consumers: Scale message processing across multiple instances for high throughput.
• Dead-Letter Queues (DLQs): Handle and monitor undeliverable messages to prevent data loss.
• Saga Pattern: Coordinate complex, multi-step business processes using state machines with MassTransit.
• Idempotent Consumers: Ensure safe message processing with at-least-once delivery guarantees.
• Use Case: Develop a microservices-based e-commerce platform where order placement triggers events for inventory, billing, and shipping services, with robust error handling and compensation logic.

Quick Start

Use the dotnet-messaging-patterns skill to implement publish/subscribe using MassTransit with RabbitMQ.
