Learn ASP.NET Core SignalR step by step: build real-time chat and live notifications in C# with hubs, groups, auth, and scaling. Start coding today! Users expect apps to update on their own. A chat message should show up as soon as it is sent. An order status should change without a page refresh. If your app still polls the server every five seconds, you are wasting bandwidth and your users can feel the delay. ASP.NET Core SignalR is Microsoft's built-in library for real-time web features in C#. It lets the server push data to connected clients as soon as something happens. In this SignalR tutorial you will build two common real-time features: a multi-room chat application and user-targeted live notifications . The examples use .NET 10 and cover strongly typed hubs, groups, authentication, sending messages from background services, and scaling out. Along the way we explain why each piece works the way it does, so you can avoid the mistakes that tend to show up in production....
