Show HN: BoardGames: 100% realtime C#/WASM app with just 35 LOC of realtime code

"Board Games" is a new Fusion + Blazor sample and a fully functional web app allowing you to play real-time multiplayer board games.

Ok, it's real-time, but what's so new there? The implementation cost of real-time updates. Everything you see in this sample required me to write just ~ 35 extra lines of code!
