Blazor is the UI framework, the underlying connection is actually handled by SignalR which uses several transports from WebSockets (by default) to server-sent events and long-polling. The Blazor server framework and JS already handle connection drops automatically but you can also add your own logic (like forcing a page refresh if it takes too long).
