3. What Is SignalR
• Real-time apps
• Server -> Client
• Client -> Server
• Hubs
• The bridge between clients and server
• Takes the complexity out of Web Sockets and fallback methods
• Near instant
• Limits?
• Does not really scale well without (Redis backplane or Azure SignalR Service)

4. What Is Azure
SignalR
• Is an Azure Service: You
dont have to have your
own server
• Up and going in minutes
• Modes
• Default – ASP.net
Core
• Serverless – Azure
Functions
• Classic -> Mixed -
Not Recommended

5. What can SignalR Do
• Broadcast to all Clients
• Collect users in groups to send mesage
• Send mesage to a specific user
• What is a message  just text aka json
• Can implement your own authentication – middleware

6. Scenarios to use SignalR
• HelpDesk and Chat based systems
• Online HTML Games
• Anytime you want a user to get real time updates
• Instead of polling
• Live Dashboards – Think Flight status page with live updates
• Charts
• The limit is your imagination

7. Lessons Learned
• Objects instead of single
values – Does not break
on change
• Some times its good to
pay for stuff (Use
Standard more stable)
• One Service per
developer. Things get
mixed up
