In this section, I’m going to cover how you can use SignalR outside of a Hub. In most asp.net core applications, you will likely want to communicate with the connect clients from within your application but outside of a Hub. You can accomplish this by using the HubContext.

For example, an ASP.NET Core MVC Controller or any other class that is instantiated by ASP.NET Core’s Dependency Injection.

The HubContext allows you to send messages to your connected clients. It has many of the same features to communicate with clients as when you are inside of a Hub.
