This week, Fritz cranks up the interaction with the audience by adding an overlay to the stream that the chatroom could interact with. We learn to use SignalR to interact with websites LIVE and how we can make our applications more collaborative.

Questions:

00:19:01 - What are the prerequisites for this stream?

00:27:50 - Are there any plans to make this less JavaScript and more C#?

00:33:23 - Why 'invoke' there and not 'send'?

00:33:49 - Does this work with ReactJS?

00:50:21 - Is SignalR the right framework for WebSocket connections between .net applications?

00:56:29 - Can i implement SignalR with Azure Functions?

00:57:43 - How about SignalR vs GRPC?

00:59:07 - How can you host the SignalR App at the Cheapest cost possible?

01:05:10 - Can I host SignalR on a VPS or is it just for cloud?

01:06:10 - Will SignalR work as mobile app notifications?

01:20:39 - In the SignalR docs it reports 10 concurrent session limit on IIS. Why is that?

01:34:22 - Does Apple M1 concern the .NET team? Will it affects the speed of development process?

01:37:15 - Does SignalR provide good performance for a feature like instant messaging?

01:47:47 - How would you do app to app connections with websockets? Any tips on where to start?
