How do you handle real-time updates (WebSockets/SignalR) in a MAUI app?

Use the SignalR client (Microsoft.AspNetCore.SignalR.Client) or ClientWebSocket for push updates. Start the connection in a service, subscribe to hub events, and marshal updates to the UI thread. Manage the connection lifecycle with app state—reconnect on resume, stop or background appropriately on sleep.

var hub = new HubConnectionBuilder()
    .WithUrl("https://api.example.com/chat").WithAutomaticReconnect().Build();
hub.On<string>("Receive", msg =>
    MainThread.BeginInvokeOnMainThread(() => Messages.Add(msg)));
await hub.StartAsync();
