如何从Linq2Sql查询填充POCO(子)IList属性？

public class Parent
{
    public int ParentID { get; set; }
    public string ParentName { get; set; }
    public IList<Child> Children { get; set; }
}

public class Child
{
    public int ChildID { get; set; }
    public string ChildName { get; set; }
    public int ParentID { get; set; }
}

public class MyDataContext : DataContext
{
    public Table<Parent> Parents;
    public Table<Child> Children;
}

using (MyDataContext context = new MyDataContext())
{
    var parents = context.Parents.Select(p => new Parent
    {
        ParentID = p.ParentID,
        ParentName = p.ParentName,
        Children = context.Children.Where(c => c.ParentID == p.ParentID).ToList()
    }).ToList();
}
