ASP.NET SignalR is a .NET library that makes it simple to add real-time web functionality to ASP.NET (System.Web/Katana) applications, letting server-side code push content to connected clients instantly. It abstracts transports like WebSockets and long polling behind a simple hub programming model.
Use cases
- push live updates from server to browser clients
- build a real-time chat application in ASP.NET
- stream dashboard or monitoring data without page refreshes
- implement high-frequency updates for real-time games
- replace ajax long polling with a simpler push model
- broadcast notifications to all connected clients
When to choose
- you maintain a legacy .NET Framework / System.Web or Katana ASP.NET app that needs real-time push
- you want a simple hub-based RPC model for server-to-client messaging
- you need automatic transport fallback (WebSockets, SSE, long polling)
When to avoid
- you are starting a new project - use ASP.NET Core SignalR instead, as this repo is in maintenance mode with no new features
- you need a managed, scalable hosting option - consider Azure SignalR Service
- your stack is not .NET
