core issues 

when using .tolist not able to access the key value

bcz of using .tolist(). so then i used firstordefault()

 var resendotp = _context.Members.Where(x => x.IsActive == true && x.UserId== userMerber.UserId).FirstOrDefault();

                if (DateTime.Now > resendotp.OtpsentDate.Value.AddMinutes(5))

here if we use tolist result will be differenct so used firstordefault
