Is your feature request related to a problem? Please describe the problem.
As usual with .NET, I had to read the code to discover a bunch of important stuff about the semantics of the APIs offered. In this case: HubConnection.Reconnecting takes a Func<_, Task>; what happens to the Task? Does anything block on it? This should surely be documented.
