Why do we need real-time?New emailTwitter/Facebook updatesStock Ticker/Live AuctionsGame ScoresReal-time NotificationsTurn-by-Turn GamesCollaborationProgress BarsAnd obviously, Chat

Existing TechnologiesHTTP – purely Request/Response protocolInternet – stateless; servers don’t call your app backConsumption model .. But we’ve learnt tricksPeriodic/Ajax Polling – not real-time, bandwidth misuse Image courtesy

Existing Technologies ..Contd. Use plugins like SL/Flash – to access sockets Native Web Sockets help – but low level & support flaky Long Polling – server does not respond unless X happens, client polls after data receive or time-out Image courtesy @maartenballiauw

Enter SignalRAn async, persistent connection/signalling library for .NET ... aids in building real time, multi-user connected applications.Persistent client-server connection over best transport .. Abstracts away the transport layer.From ASP.NET team-members (Damian Edwards & David Fowler) .. Not officially MSFT product, but OSS Boom! https://github.com/SignalR/SignalRhttp://jabbr.net/#/rooms/signalSignalR is broken up into a few packages on NuGet: SignalR - Package for SignalR.Server and SignalR.Js SignalR.Server - Server components needed for SignalR endpoints SignalR.Js - Javascript client for SignalR SignalR.Client - .NET client for SignalR SignalR.WP7 & SignalR.Silverlight – For the cool folks  SignalR.WebSockets - WebSocket Transport for SignalR

Live DemosWhoa .. What happened here?Client calls server; Server calls client; seamlesslyNo polling, at least in our codeServer maintains Clients .. Broadcast to all, group or individual clientsLow level – PersistentConnection; more controlAbstraction – Hub; easier to use

Where does this fit?Other technologies have solved this problemSocket.IO is a client-side Jscript library that talks to node.jsNowjs supports namespace sync between client-serverPrimary SignalR advantages → Simplicity & ease of use → Works natively in .NET → Works out of browser → Supports Web Sockets through a NuGet package [ASP.NET 4.5/IIS 8 on Win8 only] WebSocket is a web technology providing for multiplexing bi-directional, full-duplex communications channels over a single TCP connection. Still being standardized. → Works on other platforms
