What is real-time functionality? It's the ability to have your server-side code push content to connected clients as it happens, in real-time.## Part of the ASP.NET FrameworkSignalR hubs can be written in C# code and added to your ASP.NET app, alongside your pages and APIs.The simple programming model integrates seamlessly with other ASP.NET features like dependency injection, authentication, authorization, and scalability.## What can you do with ASP.NET and SignalR?While chat is often used as an example, you can do a whole lot more. Any time a user refreshes a web page to see new data, or the page implements Ajax long polling to retrieve new data, it's a candidate for using SignalR.SignalR also enables completely new types of applications that require high-frequency updates from the server, such as real-time gaming.## Open source, open protocolSignalR is open-source on GitHub, just like the rest of .NET. In addition to the source code, the protocol specification for communication between hubs and clients is open too.## Connect from everywhereWith client SDKs for JavaScript, .NET (C#, F#, and Visual Basic), Java, and Swift, you can connect to your SignalR hub and start receiving real-time messages on almost any platform including web, mobile, desktop, and games.SignalR will use WebSockets when it's available, and gracefully falls back on other technologies when it isn't, while your application code stays the same.## SignalR is fast and scalableLike the rest of ASP.NET, SignalR was built for high performance and is one of the fastest real-time frameworks around.Scale out across servers with built-in support for using Redis, SQL Server, or Azure Service Bus to coordinate messages between each instance.## Azure SignalR serviceThe same call, in code.
The capture above came back as markdown. These examples add a key, so you get browser rendering, proxies, and concurrency on signalr.net.
