Broadcasting Real-Time Communication Using SignalR

In this chapter, you will be introduced to SignalR, a technology that enables a developer to create a service that can have multiple clients and broadcast messages to all of them or a subset of them live in real time.

This chapter will cover the following topics:

  • Understanding SignalR
  • Building a live communication service using SignalR
  • Building a web client using the SignalR JavaScript library
  • Building a .NET console app client
