Durable messaging in .NET event-driven architectures is implemented using patterns like publish/subscribe, competing consumers, and dead-letter queues. This ensures reliable delivery across distributed systems even when services are temporarily unavailable.

Orchestrating multi-step business processes in distributed .NET systems is handled using the Saga pattern with state machines. This coordinates complex workflows for choreography and orchestration across multiple independent services.

Message failures and deduplication in RabbitMQ or Azure Service Bus are handled using dead-letter queues and idempotency patterns. Dead-letter queues capture failed deliveries, while idempotency ensures safe message processing through deduplication.

MassTransit works with Azure Service Bus and RabbitMQ for implementing publish/subscribe and competing consumers patterns. It provides abstractions for distributed message handling across these messaging platforms in .NET.

Delivery guarantees available for event-driven .NET microservices include at-most-once, at-least-once, and exactly-once delivery. These guarantees define how reliably messages are processed when coordinating events like OrderPlaced across independent services.

Message envelopes in distributed .NET messaging systems address cross-cutting concerns for robust communication. They standardize message structure, supporting reliable routing and processing across publish/subscribe and competing consumer architectures.
