{
    var connectionId = Context.ConnectionId;
    var user = Context.User.Identity.Name; // Context.User is NULL         


        

Answer 1

Pass your username using query string.

Client

First set query string

string url = @"http://localhost:8080/";
var connection = new HubConnection(url);
_hub = connection.CreateHubProxy("TestHub");
connection.qs = { 'username' : 'anik' };
connection.Start().Wait();

Server

public override Task OnConnected()
{
    var username= Context.QueryString['username'];
    return base.OnConnected();
}
