Azure Service Bus Messaging is an asynchronous messaging cloud platform that enables you to send messages between decoupled systems. Microsoft offers this feature as a service, which means that you do not need to host any of your own hardware in order to use it.

Refer to docs.microsoft.com to learn more about Service Bus.

This library is built using .NET Standard 1.3. For more information on what platforms are supported see .NET Platforms Support.
