One console app runs the same five orders, one of them a poison order, through a RabbitMQ quorum queue (ack, reject and requeue, dead-lettered by delivery limit), a Kafka topic (manual commits, seek-back retries, an app-written dead-letter topic, a second consumer group and a replay by timestamp) and a RabbitMQ stream read twice from the first offset. RabbitMQ.Client 7.2.2, Confluent.Kafka 2.15.1. docker-compose.yml starts rabbitmq:4.3.6-management and apache/kafka:4.3.1 (KRaft, no ZooKeeper). Three Testcontainers tests (xunit.v3.mtp-off 4.0.1, Testcontainers 4.15.0) assert every outcome; the test project prints each test's console output in the dotnet test log.
Testcontainers.Kafka 4.15.0 writes KAFKA_ADVERTISED_LISTENERS with a trailing comma, and apache/kafka:4.3.1 exits with "Configuration 'advertised.listeners' values must not be empty". The upstream fix (testcontainers-dotnet PR 1772) is not released yet, so the Kafka test's start command drops the comma from the generated startup script.

dotnet-client-libraries/RabbitMqVsKafka, a new folder for the new article "RabbitMQ vs Kafka for .NET Developers".The same order-processing producer and consumer run on both brokers: a RabbitMQ quorum queue with acknowledge, reject and dead-lettering, a Kafka topic with offset commits, seek-back retry, a dead-letter topic, a second consumer group and replay by timestamp, and a RabbitMQ stream read twice.
docker compose up -dstarts both brokers for the console demos.dotnet testruns three integration tests with Testcontainers (Docker required); CI runs them on its ubuntu runners.The article is not published yet. This PR stays open until the article goes live.
