Are you sick of that dreaded page refresh? Want to turn your Web application up to 11? If you've answered yes to either question, SignalR is for you. With SignalR, you can provide content to your users in real-time, all from ASP.NET. Most importantly, it's compatible with browsers ranging all the way back to IE6! SignalR uses WebSockets on supported browsers and will fall back to server-side events, Forever Frame, or AJAX long polling if needed. This means you can use a single library and not have to worry about that minutia.
