NetMQ is a 100% native C# port of the lightweight messaging library ZeroMQ for .NET.
NetMQ solves the problem of adding sophisticated messaging capabilities to .NET applications without requiring external dependencies or native libraries. It extends standard socket interfaces with asynchronous message queues, multiple messaging patterns, message filtering through subscriptions, and seamless access to multiple transport protocols. By porting ZeroMQ directly to C#, the tool eliminates the need to interoperate with native ZeroMQ binaries while preserving the messaging patterns and abstractions that make ZeroMQ valuable.
Developers should choose NetMQ when building .NET applications that require reliable inter-process or network communication with support for patterns like request-reply, publish-subscribe, and push-pull. It suits projects where you want ZeroMQ's messaging model without managing native dependencies. The project maintains two versions: a stable version and a newer version with obsolete code removed, allowing teams to choose based on their migration readiness.
The project maintains active engagement through a mailing list for community discussion and accepts contributions following a formal specification process. Documentation is available through a dedicated site and supplemented by community blog posts covering socket types, polling, and messaging patterns. The maintainer provides consulting services, indicating sustained involvement with the project's direction and real-world usage scenarios.
