Cambion is a lightweight distributed application framework with multiple and pluggable backends, providing a set of convenience functions for event handling. If you have one application that needs to talk to another application, either on the same computer, or even on a different computer, you can't use the default loopback backend provided with Cambion. This transport provider uses Azure Service Bus to send data between instances of Cambion.
Cambion.Transport.AzureServiceBus is available on NuGet so you can install it in the NuGet Package Manager Console:
Install-Package Whitestone.Cambion.Transport.AzureServiceBus
Documentation for the AzureServiceBus transport is available on the Cambion documentation site
