Ups.... if so a generic class would be better
BaseClass<T>
public virtual IColllection<T> Collection { get;set; }
ChildClass: BaseClass<ChildClassCollection>
then you can map the collection to internal field and use Linq OfType<T> to
return the expected strongly-typed enumerable.
Obviously there are others solutions without use 'new'.
