Broadcast an event to all consumers using an Azure event-hub

I want to use the Azure service-bus event-hub to send a single message to many instances of an application but not with the goal of load-balancing.

What I want to do is broadcast a message to all application instances regardless of which partition it is.

I have heard that I can do it using consumer groups but I couldn't find any tutorials on it.

This scenario is relatively straight forward assuming you can consistently inject the same unique name into each application instance such as on the command line. If you want to use an EventProcessorHost just specify a different Consumer Group string for each application instance in the constructor. Then it will "load balance" to only one machine per group causing each instance to receive all the messages. There are fancier things you can do if you end up with more machines

I suggest looking at this for some additional discussion of Consumer Groups, or this which discusses using EventHubs as a backplane (basically what you're doing).
