SignalRType
About
SignalR is a library for 
ASP.NET that enables real-time two-way communication between servers and clients.
It supports multiple transport methods (
WebSockets, Server-Sent Events, long polling) with automatic negotiation, provides a Hub API for calling methods from server or client, handles connection lifecycle, supports groups and broadcast messaging, and scales via backplanes and 
Azure SignalR Service.
WebSocket is a communication protocol that enables persistent, full-duplex data exchange between a client and a server over a single TCP connection.
It maintains a long-lived connection that allows low-latency message exchange, supports both text and binary frames, minimizes overhead by avoiding repeated request headers, and enables servers to push data to clients in real time.
