using System.Collections.Generic;
using System.ComponentModel;
using System.Linq.Expressions;

using DanielVaughan.MetaGen.Demo.Metadata;

namespace DanielVaughan.MetaGen.Demo

	public class Person : IPerson, INotifyPropertyChanged
	{
		string name;

		public string Name

				return name;
			}
			set
			{
				name = value;
				OnPropertyChanged(PersonMetadata.MemberNames.Name);

		{
			get
			{
				return address;

			set
