dotnet-messaging-patterns
Durable messaging patterns for .NET event-driven architectures. Covers publish/subscribe, competing consumers, dead-letter queues, saga/process manager orchestration, and delivery guarantee strategies using Azure Service Bus, RabbitMQ, and MassTransit.
Out of scope: Background service lifecycle and IHostedService registration -- see [skill:dotnet-background-services]. Resilience pipelines and retry policies -- see [skill:dotnet-resilience]. JSON/binary serialization configuration -- see [skill:dotnet-serialization]. In-process producer/consumer queues with Channel<T> -- see [skill:dotnet-channels].
Cross-references: [skill:dotnet-background-services] for hosting message consumers, [skill:dotnet-resilience] for fault tolerance around message handlers, [skill:dotnet-serialization] for message envelope serialization, [skill:dotnet-channels] for in-process queuing patterns.
Messaging Fundamentals
Message Types
| Type | Purpose | Example |
|---|---|---|
| Command | Request an action (one recipient) | PlaceOrder, ShipPackage |
| Event | Notify something happened (many recipients) | OrderPlaced, PaymentReceived |
| Document | Transfer data between systems | CustomerProfile, ProductCatalog |
