How to use MSMQ in DotNet?
You can use MSMQ in dotnet with small lines of code, Just Declare your MessageQueue object and call Receive and Send methods. The Message itself can be normal string or binary data.
What is MSMQ in messaging?
MSMQ has it's own limitations. MSMQ 1.0 and MSMQ 2.0 had a 4MB message limit. This restriction was lifted off with MSMQ 3.0. Message oriented Middleware (MOM) is a concept that heavily depends on Messaging. Enterprise Service Bus foundation is built on Messaging. All these new technologies, depend on Messaging for asynchronous data delivery with reliability.
What is queue manager?
As its name states, it's just a queue manager. You can Send objects (serialized) to the queue where they will stay until you Receive them. It's normally used to send messages or objects between applications in a decoupled way. It has nothing to do with webservices, they are two different things.

When to use message queues?
You would want to use message queues when there is a possibility that the other communicating process may not be available, yet you still want to have the message sent at the time of the client's choosing. Delivery will occur the when process on the other end wakes up and receives notification of the message's arrival.
What is MSMQ in SQL Server?
MSMQ was fairly unique in that it supported distributed transactions, meaning that database operations in SQL Server and messaging operations through the queues could all be combined in one atomic transaction so that either everything succeeded, or everything failed. Most other message transports do not support distributed transactions, but if you’re using NServiceBus, we have a component called the Outbox that simulates the reliability of a distributed transaction by piggybacking on a local database transaction. See our blog post What does idempotent mean? for more details.
What is MSMQ messaging?
MSMQ is a distributed or federated messaging system where every server hosts the queue infrastructure, and outgoing messages are sent locally before being delivered to their ultimate address . In contrast, most other messaging systems are centralized or broker-based, meaning there is only one logical queue system, which usually exists in a cluster to provide for high availability. This makes scale-out quite a bit easier as multiple physical endpoint instances can both compete for messages on the same queue using the competing consumers pattern.
What caused MSMQ to die?
The real cause of MSMQ’s demise is .NET Core. On October 14, 2019, Microsoft announced that .NET Core 3.0 concludes the .NET Framework API porting project, and closed the issue for adding .NET Core support for the System.Messaging namespace. But even before the official announcement, Damian Edwards basically said as much at an NDC Oslo panel discussion on the future of .NET in June 2019.
Where is MSMQ located?
Microsoft Message Queuing, better known by its nickname MSMQ, passed away peacefully in its hometown of Redmond, Washington on October 14, 2019, at the age of 22. It was born in May 1997 and through 6.3 versions lived a very full life, bringing the promise of reliable messaging patterns ...

What is WCF in MSMQ?
The final option was to use Windows Communication Foundation (WCF). In theory this allows messages that were previously being sent to MSMQ to be rerouted to any other message queueing system merely by changing a configuration setting. But the necessary plugins for non-Microsoft technologies were not widely available, so WCF never fulfilled that promise. And the .NET Core version of WCF is neither production ready nor does it have MSMQ on the current roadmap.
When was MSMQ created?
MSMQ was created in 1997 and has been available as an optional OS component since Windows 95 and Windows NT 4.0. (The current version of Windows is derived from Windows NT.) This ubiquity made it the default choice for many companies, especially in the early years where there were few competitors outside of Java’s proprietary JMS technology.
Is JMS proprietary?
Though, accusing JMS of being proprietary is a bit misleading. While it was only available for Java, it could run on any operating system. Conversely, MSMQ was available for any COM-compatible programming language, but could only run on Windows. And for any programming language to be viable on Windows, it needed to be able to access COM libraries.
Is MSMQ available for.NET Core?

🔗Ok, But Seriously…
🔗So What Do I Need to do?
- What if you have a current system already running on MSMQ? What do you do then? First of all… If you’re comfortable with your system continuing to run on .NET Framework, then you don’t really need to do anything. Microsoft will continue to support MSMQ for years and years, as long as you don’t care about any of the improvements promised in .NET 5 and beyond. If you dowant to stay …
🔗Our Future Plans
- As far as Particular Software is concerned, we don’t yet have any concrete plans to discontinue our own support for MSMQ systems. At this time, you can still build and maintain NServiceBus systems with the MSMQ transport using NServiceBus version 7, which targets .NET Framework 4.5.2+ and .NET Standard 2.0, which we will support for as long as NServiceBus 7 is supported. …
🔗Summary
- In 2007, the very first version of NServiceBus was a wrapper around MSMQ. Support for other message transports was added through the years. MSMQ is an important part of our history, so we have mixed feelings about its passing. But we feel a measure of relief as well, because for about a year the future of MSMQ was murky at best. Customers would ask us if MSMQ was dea…
