Message Brokers like RabbitMQ are the most common solution for decouple the communication between two different application and add an intermediary between them. With this solution there are many benefits, like asynchronous communication, indipendent protocols between the applications, definition of rules for routing messages and in case of RabbitMQ an efficient protocol like AMQP to...

RabbitMQ consumer with C#
In the previous post I talked about a RabbitMQ publisher and how we can implement it with C#. The next step is implement a consumer and we'll see how we can do that efficiently; unlike the publisher, the consumer has more implication and as we'll see, we can consume messages from RabbitMQ in different ways. The... Continue Reading →
