I looked into 2.4 sample business objects and found that all they contain
same code, like in Customer.cs

public override CustomerEntity Entity
		{
			get
			{
				if (this._entity == null)
				{
					this._entity = this.CreateEntityObject();
				}
				this._entity.SetDataRow(this.DataRow);
				return this._entity;
			}
			set { this._entity = value; }
		}
		private CustomerEntity _entity;

There is no need to duplicate code in each class since Entity is generic type.
So this code can be placed to BusinessObjectGeneric class
Entity property getter and setter methods.

Why code is duplicated in every business object in sample ?
How to remove DataRow usage ?
