FormsIdentity & FormsAuthenticationTicket not defined in project -- please help

Hi There,

I am trying to use these properties ( FormsIdentity & FormsAuthenticationTicket ) in my function and I get the error saying they are not defined, I have imported all the namespaces that I thought I needed and it still does not work in my global .asx file.

                    Dim ticket As FormsAuthenticationTicket = id.Ticket
                    Dim userData As String = ticket.UserData
                    Dim roles As String = userData.Split(","c)
                    HttpContext.Current.User = New GenericPrincipal(id, roles)
