How to fill bool property with default value

[Vasile Bicherschi]

Ex:

    class User
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public IsActive { get; set; } = true;
    }

           GenFu.Configure<User>()
                .Fill(g => g.FirstName , () => $"FirstName-{Guid.NewGuid()}")
                .Fill(g => g.LastName , () => $"LastName -{Guid.NewGuid()}")
                .Fill(g => g.IsActive).WithRandom(new [] {true, false});

var users = A.ListOf<User>(20);

All users have the IsActive property set to default value (IsActive == true);
In debug, the setter property are never called.
