Is there a way to specify a universal exception handler for SignalR client message handlers?

I am using the C# SignalR client library, and I caused an exception inside one of my message handlers. (Oops!) I noticed that it silently abandons the handler. Is there any way to specify a general exception handler for when a given delegate fails to handle it? Or do I need to wrap each handler individually in a try-catch block?
connection.On("CreateMessage", () => throw new Exception("Oops!"));

I call
connection.On(...)a dozen times to map a dozen handlers. Do I have to put atry-catcharound the bodies of every single handler? Or is there way to register a global exception handler for any message handler that throws an exception?Do I have to put a try-catch around the bodies of every single handler?
