Microsoft announced the availability of SignalR Service bindings in Azure Functions so app engineers, like the app developers at New Media Aid, have the ability to push messages and content updates in real-time to connected clients.
Bring your ASP.NET apps to life with SignalR
Today's modern apps are expected to deliver up-to-date information without hitting a refresh button. Add real-time functionality to your dashboards, maps, games and more. 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 Framework
SignalR 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 protocol
SignalR 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 everywhere
With client SDKs for JavaScript, .NET (C#, F#, and Visual Basic), and Java, 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 scalable
Like 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 service
You can host the SignalR app yourself or use Azure SignalR Service for a fully managed platform. Azure SignalR Service handles concerns like performance, scalability, and availability and has a 99.9% service-level agreement.
SignalR is an open-source real-time communication library for .NET applications developed by Microsoft. It enables server-side code to send asynchronous notifications to client-side web applications, allowing real-time communication between the server and clients.
SignalR uses web sockets as the default transport mechanism to provide real-time communication between client and server, but it can automatically switch to other transport mechanisms, such as Server-Sent Events (SSE) or long polling, depending on the browser and server capabilities.
SignalR also provides several features that make it easier for developers to build real-time applications, such as automatic reconnection, group communication, and security measures. It can be used to build a wide range of real-time applications, including chat applications, online games, and collaboration tools.
SignalR supports both .NET Framework and .NET Core, and can be used with a wide range of front-end frameworks, including Angular, React, and Vue. It is available as a NuGet package and can be installed using the Package Manager Console or the Visual Studio NuGet Package Manager.
SignalR is an open-source library for building real-time web applications in .NET. It provides developers with an easy way to add real-time communication to their applications, allowing users to receive live updates and messages without the need to refresh the page.
SignalR uses several different techniques to enable real-time communication, depending on the capabilities of the client and server. It uses WebSockets when available, falling back to Server-Sent Events (SSE) and long-polling for older browsers. This makes it a reliable solution that can work in a wide range of environments.
With SignalR, developers can create applications that support real-time data streaming, instant messaging, and collaborative features. It can be used in a variety of scenarios, including gaming, chat applications, monitoring and analytics tools, and more.
SignalR is available as a NuGet package for .NET applications, and it supports a range of platforms and frameworks, including ASP.NET, ASP.NET Core, and Xamarin. It also provides client libraries for popular front-end frameworks, such as React, Angular, and Vue.js.
