This SDK post looks like a story written in C#-speak:

delivery1.Location = new Organization(“General Hospital”);
delivery1.TimeOfDelivery = new ApproximateDateTime(new ApproximateDate(2008, 11, 1), new ApproximateTime(00, 15, 35));
delivery1.LaborDuration = 123;

….

delivery1.Baby = new Baby();
delivery1.Baby.Name = new Name(“Thomas John Andersen”);
delivery1.Baby.Gender = new CodableValue(“Male”, new CodedValue(“male”, “gender-types”, “wc”, “1″));
delivery1.Baby.Weight = new WeightValue(2.5, new DisplayValue(5.5, “pounds”));
delivery1.Baby.Length = new Length(0.46, new DisplayValue(18, “inches”));
delivery1.Baby.HeadCircumference = new Length(0.31, new DisplayValue(12.4, “inches”));

pregnancy.Delivery.Add(delivery1);

A strong-typed class library for all your life ! Brilliant ! :)
