what code have you written?

It appears that if the user isn't authenticated, you can't make the cast. If you try you will get the error: " Unable to cast object of type 'System.Security.Principal.GenericIdentity' to type 'System.Web.Security.FormsIdentity'. ". However, once authenticated, the cast is valid. Hope that helps. try to put your code in condition that checks the user is already authenticated and not anonymous. if ( HttpContext.Current.User != null && HttpContext.Current.Identity is FormsIdentity ) { // your code follows } else { // the user is not yet authenticated and // there is no Forms Identity for current request }

I have always this Proplem : 'Unable to cast object of type 'System.Security.Principal.GenericIdentity' to type 'System.Web.Security.FormsIdentity'.' This is my code : FormsIdentity id = (FormsIdentity)User.Identity; FormsAuthenticationTicket ticket = id.Ticket; Response.Write(" TicketName: " + ticket.Name); Response.Write(" Cookie Path: " + ticket.CookiePath); Response.Write(" Ticket Expiration: " + ticket.Expiration.ToString()); Response.Write(" Expired: " + ticket.Expired.ToString()); Response.Write(" Persistent: " + ticket.IsPersistent.ToString()); Response.Write(" IssueDate: " + ticket.IssueDate.ToString()); Response.Write(" UserData: " + ticket.UserData); Response.Write(" Version: " + ticket.Version.ToString()); The Application uses Form Authentication at the moment .
