After the messages are delivered RabbitMQ deletes them from it’s own storage. RabbitMQ stores these messages on it’s local storage and delivers them to another microservice which is called as Consumer. So this microservice is called as a Publisher. In simple words, a microservice publishes messages to RabbitMQ. RabbitMQ ensures that the messages are never lost and get delivered to the respective consumer. RabbitMQ is an open-source and most popular message broker service which you can use for performing asynchronous communication between microservices. #MASSTRANSIT SET RESPONSE ADDRESS CODE#You can find this tutorial’s the complete Source Code at my GitHub Repository. We will change this communication to Asynchronous one by using RabbitMQ which is an open-source message broker.

The global.asax is just like the DashboardApplication in the morails sample and the WebAppContainer.cs again is similar to the monorail sample without any references to monorail! The message are exactly the same and the web config has the castle section definition and castle section inserted into a default web.config file. It references the mass transit dlls (mt.sb., mt.sb.msmq, mt.WindsorInt) and the appropriate castle dlls. ![]() The project contains 6 files (well 9 really)ĪsynchWebForm.aspx (marked as Async=”true”) As i am working on a project not using monorail (and there may be a couple of others doing the same) i thought i would make demo project using asp.net, oldskool. #MASSTRANSIT SET RESPONSE ADDRESS DOWNLOAD#The Web sample in the MassTransit download that i talked about in the last post used MonoRail. ![]()
