Answer 1

Since your question has two parts:

1. Your method for storing additional information is correct

2. You can't proceed unless you see the actual error, in order to see the details you need to add this where you create the user.

   public override int SaveChanges()
   {
       try
       {
           return base.SaveChanges();
       }
       catch (DbEntityValidationException ex)
       {
           // Retrieve the error messages as a list of strings.
           var errorMessages = ex.EntityValidationErrors
                   .SelectMany(x => x.ValidationErrors)
                   .Select(x => x.ErrorMessage);
   
           // Join the list to a single string.
           var fullErrorMessage = string.Join("; ", errorMessages);
   
           // Combine the original exception message with the new one.
           var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);
   
           // Throw a new DbEntityValidationException with the improved exception message.
           throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors);
       }
   }
