  c# ajax asp.net-mvc signalr
  I have an ASP.NET MVC3 application.If my application had a large number of users – let’s say 100,000 – hypothetically, if all users were talking to each other and I used SignalR, would there be 100,000 long polling connections? Would these cause some sort of denial of service? Should I be using AJAX HTTP instead? Or would SignalR be smart enough to release the connection to resource pool when no activity is found for certain period of time? When would using signalR for chat be recommended for ch

  asp.net-mvc-3 .net-4.0 signalr signalr-hub signalr.client
  This thing is dragging me nuts. I have a .net 4.0 console app and I have an MVC web app. javascript clients can connect and talk to the server – no problems here… but my .net client throws System.AggregateException with InnerException = “Unexpected character encountered while parsing value: <. Path…so I created an empty MVC3 app, added SignalR libraries, and .net client surprisingly connects to that. But for some reason it doesn’t to the other one. I’ve checked everything, both MVC3 apps

I’m following this guide: http://www.asp.net/signalr/overview/signalr-20/hubs-api/hubs-api-guide-net-client#callserverThis is what I have: _hubConnection = new HubConnection(_baseUrl); // “http://localhost:3806″_hubProxy = _hubConnection.CreateHubProxy(“AppHub”);_hubConnection.Start().Wait();The hub lives inside of the same project – it’s an MVC application with forms authentication.
