Validated and performant MQTT client fast-tracks IoT application development cycles.

5 April 2023 – Landshut, Germany - HiveMQ, a global leader in enterprise MQTT solutions, today added a C# Client to the open-source HiveMQ MQTT Client Libraries. The new client appeals to any organization building IoT applications using the Microsoft .NET framework, extending the MQTT ecosystem with a reliable, performant and fully-supported client.

All of the clients in the HiveMQ MQTT Client Libraries, including the popular HiveMQ MQTT Java Client, work with any MQTT broker to fast-track application development cycles and ensure long-term flexibility for IoT deployments.

The goal is to help our customers build IoT applications faster, and on the device side, help them migrate data from device to cloud seamlessly with MQTT.”
