Extension ID

com.castsoftware.dotnet.rabbitmq

What’s new?

See RabbitMQ for .NET - 1.0 - Release Notes for more information.

Description

This extension provides support for RabbitMQ for .NET APIs which are responsible for publishing and receiving messages across messaging queues.

In what situation should you install this extension?

If your C# application utilizes RabbitMQ for messaging and you want to view a model that shows the message publisher and receiver objects with their corresponding links, then you should install this extension.

Technology Libraries

Library	Version	Supported
RabbitMQ.Client	upto 6.5
EasyNetQ	upto 7.5
MassTransit.RabbitMQ	upto 8.1
CAP.RabbitMQ	upto 6.0
NServiceBus.RabbitMQ	upto 8.0

AIP Core compatibility

AIP Core release	Supported
8.3.x

Dependencies

The RabbitMQ extension is dependent on following extensions to provide fully functional analysis:

CAST AIP Internal extension
Web Services Linker

Download and installation instructions

The extension will not be automatically downloaded and installed in CAST Console. If you need to use it, you should manually install the extension using the Application - Extensions interface:

What results can you expect?

Once the analysis/snapshot generation has been completed, you can view the results in the normal manner. The following objects and links will be displayed in CAST Imaging

SendLocal

.NET Producer

using System;
using System.Threading.Tasks;
using NServiceBus;

class Program
{
    static async Task Main()
    {
        Console.Title = "Samples.RabbitMQ.SimpleSender";

        #region ConfigureRabbit
        var endpointConfiguration = new EndpointConfiguration("Samples.RabbitMQ.SimpleSender");
        var transport = endpointConfiguration.UseTransport<RabbitMQTransport>();
        transport.UseConventionalRoutingTopology(QueueType.Quorum);
        transport.ConnectionString("host=localhost");
        #endregion

Receiver - IHandleMessages

.NET Receiver

namespace Receiver
{
    using System.Threading.Tasks;
    using NServiceBus;
    using NServiceBus.Logging;

    public class MyEventHandler : IHandleMessages<MyEvent>
    {
        static ILog log = LogManager.GetLogger<MyEventHandler>();

        public Task Handle(MyEvent eventMessage, IMessageHandlerContext context)
        {
            log.Info($"Hello from {nameof(MyEventHandler)}");
            return Task.CompletedTask;
        }
    }
}

Endpoint Configuration

.NET Receiver

using System;

namespace Receiver
{
    using System.Threading.Tasks;
    using NServiceBus;

    class Program
    {
        static async Task Main()
        {
            Console.Title = "Samples.RabbitMQ.SimpleReceiver";
            var endpointConfiguration = new EndpointConfiguration("Samples.RabbitMQ.SimpleReceiver");
            var transport = endpointConfiguration.UseTransport<RabbitMQTransport>();
            transport.UseConventionalRoutingTopology(QueueType.Quorum);
            transport.ConnectionString("host=localhost");
            endpointConfiguration.EnableInstallers();

            var endpointInstance = await Endpoint.Start(endpointConfiguration)
                .ConfigureAwait(false);
            Console.WriteLine("Press any key to exit");
            Console.ReadKey();
            await endpointInstance.Stop()
                .ConfigureAwait(false);
        }
    }
}

Limitations

Unknown Publisher object with no properties is created if the exchange name argument from the Publish APIs cannot be resolved
Unknown Receiver object with no properties is created if the queue name argument from the Consumer APIs cannot be resolved
