Real-time Web Applications with ASP.NET Core SignalR

on YouTube ↗50m

" summary

Covers ASP.NET Core SignalR as a rewritten, lighter library for real‑time web apps that lets server Hub classes call JavaScript and .NET clients directly. Demonstrates a working auction site using a Hub, JS and console clients, WebSockets with Server‑Sent Events/long‑polling fallbacks, and live bid updates in the browser. Discusses scaling pitfalls of sticky sessions and using Azure SignalR Service to offload connections (free tier ≈20 concurrent connections per unit, scale by adding units toward ~100).
