Scaling out ASP.NET Core SignalR using Azure Service Bus

ASP.NET Core SignalR is a super easy way to establish two-way communication between an ASP.NET Core app and its clients, using WebSockets, Server-Sent Events, or long polling, depending on the client’s capabilities. For instance, it can be used to send a notification to all connected clients. However, if you scale out your application to multiple server instances, it no longer works out of the box: only the clients connected to the instance that sent the notification will receive it.
