Forget SignalR - Start working with Azure Web PubSub

Getting real-time information on processes and operations is essential when creating convenient, user-friendly web systems. With Web PubSub, Microsoft took the next step by enabling your to leverage real-time communication right from your browser. In this session, I will show you how to use Web PubSub and discover some advanced scenarios using alternative protocols, that enable real-time communication between servers and clients.

5. SignalR Web PubSub
6. How is it different from SignalR, you ask? Well, internally, it's built on the same underlying tech, but the big difference is that there's no client requirement or protocol requirement, BYOWL (bring your own WebSocket library). - David Fowler SignalR Web PubSub
7. SignalR Web PubSub • You're already using ASP.NET or ASP.NET Core SignalR • There's a SignalR client available for your platform • You need an established protocol that supports a wide variety of calling patterns • You need to build real-time applications based on WebSocket technology • You want to build your own subprotocol or use existing advanced protocols • You're looking for a lightweight server, for example, sending messages to client without going through the configured backend
