We've included a sample ASP.NET Core project, and back end console application to show interoperability with the backplane. The only thing needed is RabbitMQ. I'd recommend using their docker image (opens new window) to spin up the broker.
You can view the MassTransit Sample here (opens new window). The sample was based off of Microsoft's chat sample (opens new window), which is nearly identical to the tutorial here (opens new window), except the only different is it's stripped down to the bare minimum (no razor Pages, bootstrap or JQuery libraries).
The other addition we added is in the Properties/launchSettings.json, which lets us start 2 profiles on different ports. Then helps simulate horizontal scaling.
# Mvc Sample
You can simulate scaleout by running the two profiles.
> cd (your cloned Sample-SignalR)\src\SampleSignalR.Mvc > dotnet run --launch-profile sample1 > dotnet run --launch-profile sample2
Now in two browser tabs, open up in each: http://localhost:5100 http://localhost:5200
Then you can type a message in each, and see them show up in the other. The backplane works!!
# Console Sample
If you have some back end services (console apps, or Mt Topshelf consumers), you might want to notify users/groups of things that have happened in real time. You can do this by running this console app.
> cd (your cloned Sample-SignalR)\src\SampleSignalR.Service > dotnet run
An type in a message to broadcast to all connections. You will see the message in your browsers chat messages
