Real-Time Messaging with SignalR

Now that we’ve created various tests, added telemetry data, monitored the solution, and scaled our services, starting with this chapter, we’ll continue creating services and using different communication technologies.

In this chapter, we’ll use ASP.NET Core SignalR. SignalR is a technology that allows us to send real-time information from services to clients. The client initiates a connection to the service, which is then kept alive to send messages to the clients as information becomes available.

In this chapter, you’ll learn how to do the following:

• Create a SignalR service
• Send real-time information to clients
• Create a SignalR client
• Use Azure SignalR Service
