Right now we have 2 static groups for long running and short running requests. You'll likely run into issues when you're using several connections in the same process. To achieve what we do with HttpClient, we need to generate a unique group name per instance of the IHttpClient.

Instead of https://github.com/SignalR/SignalR/blob/dev/src/Microsoft.AspNet.SignalR.Client/Http/DefaultHttpClient.cs#L14, we can do

public class DefaultHttpClient : IHttpClient
{
    private string _shortRunningGroup;
    private string _longRunningGroup;

    private IConnection _connection;

    public DefaultHttpClient()
    {
        string id = Guid.NewGuid().ToString();
        _shortRunningGroup = "SignalR-short-running-" + id;
        _longRunningGroup = "SignalR-long-running-" + id;
    }
    ....
}

tested a LongPolling client sending messages on four threads. All "/send" requests are sent using the shortRunningGroup while all "/poll" use the longRunningGroup. Messages are echoed and received interleaved as expected
