ASP.NET MVC Update views for specific user after change in database
I'am creating an appliaction in ASP.NET MVC 5 with SQL Server where one of the module is a News. News can be added by Administrator to main page. Users can comment the news. I would like to know how to implement real-time adding comments to news, which means that when user is reading for example news with ID=5 and somebody post a comment in this news i would like to get this comment without refreshing the page. I heard about SignalR ,but i don't know how to call update ONLY FOR USERS who are reading a specific news with for example ID=5.How to send update only for this users? Not for all logged in users, but only for a specific users which are currently on the specific news?
