ASP.NET MVC - Count number of online users - use SignalR (MVC5) - basic

ASP.NET MVC - Count number of online users - use SignalR (MVC5) - basic.
Note:
- To get right name of hub, you can view in code on link ~/signalr/hubs/
- Count is wrong because i have a project, it have same hub name and run before. the code is right.

Thanks for watching.
