  7. Why do we need real-time? New email Twitter/Facebook updates Stock Ticker/Live Auctions Game Scores Real-time Notifications Turn-by-Turn Games Collaboration Progress Bars And obviously, Chat
  8. Existing Technologies HTTP – purely Request/Response protocol Internet – stateless; servers don’t call your app back Consumption model .. But we’ve learnt tricks Periodic/Ajax Polling – not real-time, bandwidth misuse Image courtesy
  9. 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
  10. Enter SignalR An 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/SignalR http://jabbr.net/#/rooms/signal SignalR 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
  11. Live Demos Whoa .. What happened here? Client calls server; Server calls client; seamlessly No polling, at least in our code Server maintains Clients .. Broadcast to all, group or individual clients Low level – PersistentConnection; more control Abstraction – Hub; easier to use
  12. Where does this fit? Other technologies have solved this problem Socket.IO is a client-side Jscript library that talks to node.js Nowjs supports namespace sync between client-server Primary 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
