Welcome to ASP.NET forum.
Firstly, we usually use Groups to send messages to specified subsets of connected clients. You could group the clients by category, then you could call Add or Remove methods to add or remove users from a group dynamically. For more information about SignalR
Groups, please refer to this link.
Secondly, you could also broadcast messages to all connected clients, then you could filter messages from client side based on category.
