I want to write a rich domain class such as
public class Product
{
public IEnumerable<Photo> Photos {get;
private set;}
public void AddPhoto(){...}
public void RemovePhoto(){...}
}
But the entity framework (V4 code first approach) requires an ICollection type for lazy loading! The above code no longer works as designed since clients can bypass the AddPhoto / RemovePhoto method and directly call the add method on ICollection. This is not good.
public class Product
{
public ICollection<Photo> Photos {get;
private set;} //Bad
public void AddPhoto(){...}
public void RemovePhoto(){...}
}
It's getting really frustrating trying to implement DDD with the EF4. Why did they choose the ICollection for lazy loading?
How can i overcome this? Does NHibernate offer me a better DDD experience?
