I am using SignalR with mvc4 c # web application. I created the ChatHub: Hub class. Is there an event that I can log on the server side to catch all errors thrown from signalr?
All SignalR internal errors are logged separately from user errors in the hub method.
To log internal SignalR errors, see the SignalR web.config diagnostic section: https://github.com/SignalR/SignalR/blob/master/samples/Microsoft.AspNet.SignalR.Hosting.AspNet.Samples/Web.config
To register hub method invocation errors, create a pipeline pipeline module: SignalR Logging
