how to work with SignalR

In real-time the server is aware of the data updates, event occurrences, etc.This is commonly achieved through methods like continuous polling, but this is incur a lot of traffic and load to the server.

So as an alternative SignalR is popup. SignalR is an Asp.Net library, which is designed to use the existing transport technologies underneath based on the client nature and the support it offers. 

This is capable of pushing the data to a wide variety of clients. So because of this new trend developers no need to worry about which server push transport but to use and deciding on the fallback in case of unsupported scenarios.

SignalR uses transports that are required to do real-time work between client and server. Each and every transports have its own requirement. So if these requirements are not met, SignalR will attempt to use other transports (one at a time) to make its connections.
