Questions tagged [signalr]

ASP.NET SignalR is a library for ASP.NET developers that makes it simple to add real-time functionality to your web applications. That is, to have your server-side code push content to the connected clients as it happens, in real-time.

SignalR is an asynchronous library for .NET to help build real-time, multi-user interactive web applications.

SignalR lets you communicate with clients on your website in real time through the best continuous connections available between browser and server (WebSocket between Chrome and IIS 8, but long polling between Internet Explorer 9 and IIS 7.5).

SignalR allows you to call methods from the server on the client (.NET , JavaScript, Java) and reciprocally. You can invoke methods on every client or a subset of clients.

Extensive documentation and guides are found here.

SignalR can be downloaded through NuGet here.

The source code is available on GitHub.

The JavaScript client package (jQuery plugin)
