In today’s fast-paced digital world, real-time application have become essential to provide instant updates and seamless user experiences. From live chat systems and real-time notifications to collaborative tools and gaming platforms, the demand for instant communication between servers and clients is increasing. SignalR, a powerful library developed by Microsoft, plays a pivotal role in enabling real-time functionality in applications built on the .NET platform. This blog explores SignalR’s capabilities, benefits, and how it enhances real-time communication in modern applications.
What is SignalR?
SignalR is a library for ASP.NET that simplifies adding real-time functionality to applications. It enables bi-directional communications between server and client, allowing data to be pushed instantly from the server to the connected clients without polling. This makes SignalR an ideal choice for scenarios requiring live updates, such as chat applications, dashboards, and online gaming.

How SignalR Works?
SignalR uses various communication protocols to ensure compatibility with different clients and server environments. Its primary methods include:
- WebSockets: The most efficient protocol for real-time communication, allowing full-duplex communication channels over a single TCP connection.
- Server-Sent Events: A unidirectional protocol where updates are pushed from the server to the client.
- Long Polling: A fallback method where the client continuously polls the server for updates.
SignalR automatically chooses the best available transport mechanism supported by the client and server, ensuring a seamless real-time experience.
