public class WhateverHub : Hub
{
    public override Task OnConnected()
    {
        //Get the username
        string name = Context.User.Identity.Name;

        //Get the UserId
        var claimsIdentity = Context.User.Identity as ClaimsIdentity;
        if (claimsIdentity != null)
        {
            // the principal identity is a claims identity.
            // now we need to find the NameIdentifier claim
            var userIdClaim = claimsIdentity.Claims
                .FirstOrDefault(x => x.Type == ClaimTypes.NameIdentifier);

            if (userIdClaim != null)
            {
                var userIdValue = userIdClaim.Value;
            }
        }
        return base.OnConnected();
    }
}

Don't forget to use the [Authorize] attribute in your Hub class
