HVC Ws

• Project: hvc-ws

Overview

hvc-ws is a minimal WebSocket service that tracks call-room presence — "who is in this call/event right now". Clients (mobile/headset, and potentially web) connect to a per-event WebSocket, publish their own state, and receive a broadcast of every connected client's state whenever the roster changes. It is a dedicated, lightweight alternative to pushing the same roster over SignalR.

Tech Stack

• Target: .NET 8
• Microsoft.AspNetCore.OpenApi, Swashbuckle
• No EF / database — state is kept in memory (a ConcurrentDictionary).
