FluentValidation for names-CodePudding

I have the following class

public class User 
{
  string firstName;
  string lastName;
}

And for that one I want to use a regex with fluent validation to be accepted just letters and whitespaces. As a regex might be a good example but I didn't find any implementation

And I created the following validator

    public class UserValidator:AbstractValidator<User>
{
    public UserValidator()
    {
        RuleFor(x => x.Id)
            .NotEmpty()
            .NotNull();
        RuleFor(x => x.Name)
            .NotEmpty().WithMessage("Please ensure that to set a value for {PropertyName}")
            .Must(BeValidName).WithMessage("Please ensure that to set a valid value for {PropertyName}")
            .Length(3, 30);

        private bool BeValidName(string name)
    {
        return name.All(Char.IsLetter);
    }

}

But I m going to search something better :D Do you guys have any idea ? Thanks!
