Simplifying messaging in .NET with EasynetQ

EasyNetQ is a library for .NET that allows us to easily connect with RabbitMQ from an application written in C#.

RabbitMQ is an open-source implementation of the Advanced Message Queuing Protocol (AMQP) and is widely used as a messaging middleware in distributed applications.

EasyNetQ provides a high-level abstraction over RabbitMQ, simplifying the process of configuring and using queues, exchanges, and messages.

The library provides a simplified publish and subscribe model, which makes working with RabbitMQ much easier. Additionally, it also offers support for advanced messaging patterns, such as routing based on routes, subscribing to multiple queues, among others.

On the other hand, EasyNetQ automatically handles connections to RabbitMQ for us. It provides a persistent connection to RabbitMQ and takes care of reconnection in case of unexpected disconnections.

How to use EasyNetQ

We can add the library to a .NET project easily, through the corresponding Nuget package.

Using EasyNetQ is very simple. Basically, we create a communication Bus using a connectionString, and then we use the available methods.

For example, this is how we would publish a message.

var bus = RabbitHutch.CreateBus("host=localhost");

await bus.PubSub.PublishAsync(message);

And this is how we would subscribe and receive messages.

var bus = RabbitHutch.CreateBus("host=localhost");

await bus.PubSub.SubscribeAsync<MyMessage>(
	"my_subscription_id", msg => Console.WriteLine(msg.Text)
);

EasyNetQ offers many more options and functionalities, such as the ability to set up durable queues, publish messages asynchronously, and use different serialization strategies. For more information, consult the EasyNetQ documentation.
