This again identified some seams in MassTransit that were just not clean and made it difficult to take advantage of the new features. NET has gone from a limited, basic functionality library to include extensive support for the new features. RabbitMQ also got a lot more awesome, with many improvements in broker-to-client communcation, including notifications to clients as the topology of cluster nodes changes and messages flow through the broker. There is also the on-premise Service Bus option, although why somebody would run that over RabbitMQ eludes me. Support for Azure Service Bus has been limited to an external library due to the difference in messaging topology, particular the topic/queue structure that’s provided on top of SQL service broker. Cloud services are cost effective ways to host applications, but having to run a RabbitMQ cluster in IaaS can be expensive. NET developers, it’s the easiest option for systems being deployed to the cloud. Refining the transport to support push via AMQP brought the request charges down significantly, but started to identify limitations in the underlying transport model around which MassTransit was built.Īlong with the cloud came Azure and the Azure Service Bus. The first incarnation followed the same pull model that was used for MSMQ, which led to expensive running services with the cloud’s pay-as-you-go model. When support for RabbitMQ was added, it took a while to get it right and get it cloud-friendly. In addition, the big puffy cloud has become mainstream and many applications are being built cloud-first, leading to the use of push messaging systems. The new threading support has made asynchronous programming easier to understand and has greater performance with lower overhead than previous operating system threading models. The runtime and language (C#) have both evolved, adding powerful new features. NET framework since version 2.0 was released. Each of these features is great standalone, but when combined they make possible some really incredible system design options that are reliable, scalable, and supportable. What started as an abstraction layer on top of MSMQ become a comprehensive platform for creating distributed applications, including support for sagas (okay, we can call them process monitors if you prefer), message scheduling (via Quartz), and a powerful routing slip implementation that has been used as the underpinnings of a modern scaled distributed interoperability platform.
In the past seven years, MassTransit has evolved as requirements for messaging in distributed systems changed.

Since that time, NServiceBus has seen tremendous growth and is now a commercial product from Particular Software (started by Udi Dahan).
Having reviewed the source code, Dru and I came to the conclusion that we could start a new project to address our requirements using frameworks with which we were both more familiar. Originally NServiceBus was considered, but while it was open source, it was not accepting contributions at the time and was specific to less than stellar projects like Spring.NET. I had actually been using MSMQ since the late 90’s from C++, but was starting to make moves into C# and needed a managed solution. It was shortly after that Dru Sellers and I started working on a messaging library for use with MSMQ to solve problems within our respective jobs. NET community a better place for software developers.

I met a lot of great, smart people with a lot of great ideas on how to make the. MassTransit was started in 2007 after a very exciting ALT.NET meeting in Austin, TX. There will be bugs and features that are not yet complete. Early feedback is valuable, and you are encouraged to check out the early bits, but recognize that they are just that – early bits. This release is still under development and will be pushed in various pre-release forms before the final release is finished.
This article describes an upcoming release of MassTransit.
