Why couldn't you implement your own solution using WebSockets? That's what SignalR does behind the scenes.

SignalR provides transport fallback for environments where WebSockets is not available. Is wesbockets support a concern in this question, who knows? https://docs.microsoft.com/en-us/aspnet/core/fundamentals/websockets?view=aspnetcore-5.0#:~:text=ASP.NET%20Core%20SignalR%20is,where%20WebSockets%20is%20not%20available.

WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. So websockets is intended to the tasks like in this question. Answer is clearly A - Yes.

Agree with Ed64. There's even multiple examples on how to receive data, started by the server to a web browser with Web Socket protocol, that would make possible the features required in this question witout the use of signalR.
