MSMQ provides robust and easy-to-use messaging capabilities that let you send and receive messages between applications running on one machine, different machines, and even across the Internet, both synchronously and asynchronously. Unfortunately, MSMQ is notoriously underused. Find out how to get started with MSMQ and what you can do with it.

icrosoft .NET developers can use several tools to perform operations asynchronously; that is, beginning a process without waiting for the operation to complete. MSMQ has provided this facility to developers since its inception. It was especially useful for VB developers, because before MSMQ, there were very few options for managing an asynchronous process in VB. As awkward as it now seems, the most elegant solution involved using SQL Server tables to manage the 'queued' processes. Despite the multitude of tools available today for managing processes asynchronously, such as MSMQ, BizTalk, and other .NET-specific mechanisms, many developers continue to use SQL Server. This article provides an overview of MSMQ for .NET developers, including code samples for several major MSMQ features that you can use in your own applications.
At its most basic level, MSMQ is a tool for sending and receiving messages. MSMQ is powerful enough to provide near real-time message exchange throughput, depending on the machines and transports involved in the exchange, and flexible enough to provide many features required in assembling a communications infrastructure for your application system. You can send MSMQ messages across machine boundaries—including across the Internet—to queues where a receiving application can retrieve them in a prioritized first-in first-out manner. MSMQ also integrates with Active Directory to provide domain-wide queue management features.
