Is SignalR Payload agnostic?
.net, signalr, signalr-hub, signalr.client
Solution
Out of the box? No. By default SignalR only supports JSON. However, it being open source/a framework you can quite easily make small modifications (an adapter) to support other formats on your own.
Problem
Does SignalR support payloads other than those containing JSON or Text like BSON, etc.
