Centralized SignalR Hub: Real time communication

Question

Hi All,

Please guide me how to achieve centralized SignalR Hub.
        I used SignalR Hub for Chat purpose in my two application, like both has same logic for message exchange, so i wanna optimize this into single service based.
       Create a more centralized Hub class, then both application can share this service to achieve Real chat application.

My requirement is Signal R concepts common for my all web based project's it may be ASP.Net MVC, or ASP.Net.

so we gonna create some more generalized Signal R service for all application, it reside in separate like as Web service.

When i used my MVC application it serve to MVC application, parallely some other application also can use this service to achieve their task too.

MVC :  this chat service used to collaborate and interact MVC application user's only
ASP.Net : this chat service used to collaborate and interact ASP.Net application user's only


Thanks,
Jai
