SignalREventHub.ExceptionOccurred

Curently the kinds of exceptions that get thrown here are:

• ArgumentException - When an events handler has not been registered, the event names don't line up or the handler's dependencies have not all been registered.
• AuthenticationException - When an event is being raised in a context that the user is not allowed to use it.
• Exception - Any exception that happens in one of the handler's async invocations will bubble up here as well.

Simple Implementation: SignalREventHub.ExceptionOccured += (sender, args) => Debugger.Break();

However, this is also your opportunity to do logging or any other type of exception handling you would like.
