In a SignalR application on .net core, I have a working piece of code similar to the following:

```
public Task SendPrivateMessage(string user, string message)
{
    var sender = Context.User.Claims.FirstOrDefault(cl => cl.Type == "username")?.Value;
    return Clients.User(user)
                  .SendAsync("ReceiveMessage", $"Message from {sender}: {message}");
}

```

This sends a message from the currently connected user, to the specified user. 

Now I'd like to send an individual message to *every* user connected; something like the following concept:

```
public Task UpdateMessageStatus()
{
    foreach(client in Clients.Users)
    {
         var nrOfMessages = GetMessageCount();
         client.SendAsync($"You have {nrOfMessages} messages.");
    }
}

```

How can I achieve this; i.e. how can I iterate over connected users, and send individual messages to each of them?

**Edit / clarification**

As mentioned, I needed to send *individual* (i.e. specialized) messages to each connected user, so using `Clients.All` was not an option, as that can only be used to send the same message to all connected users.

I ended up doing something similar to what Mark C. posted in the accepted answer.
