"SignalR" Doesn't recognize hub

I added all SignalR component but I still have got some errors about dll recognition.

The type or namespace name 'Hub' could not be found (are you missing a using directive or an assembly reference?)

I added following libraries on NuGet;

  • Microsoft.ASpNet.SignalR
  • Microsoft.ASpNet.SignalR.Client
  • Microsoft.ASpNet.SignalR.Core
  • Microsoft.ASpNet.SignalR.JS
  • Microsoft.ASpNet.SignalR.OWin
  • Microsoft.ASpNet.SignalR.SystemWeb
  • Microsoft.Owin
  • Microsoft.Owin.Host.SystemWeb
  • Microsoft.Owin.Security

I think, I don't need most of them. 

namespace GenelProject
{
    [HubName("gsChat")]
    public class ChatHub : Hub

Why Visual Studio doesn't recognize SignalR hub when I want to use it ?

You only need the Microsoft.AspNet.SignalR.Core package. And make sure you have the namespace Microsoft.AspNet.SignalR imported with a using statement in your file.
