导航属性未加载到Poco中

Question

我在.Net 4.5中使用带有实体框架的SQLite提供程序

        conferControlEntities.Configuration.LazyLoadingEnabled = true;
        conferControlEntities.Configuration.ProxyCreationEnabled = true;
        conferControlEntities.Configuration.AutoDetectChangesEnabled = true;
        conferControlEntities.Configuration.ValidateOnSaveEnabled = true;

我也在实体框架中使用继承

所以我不能在查询中使用include，因为我不能包含派生对象导航属性

所以我在Poco类中有fillNavigationPropty方法，它会调用Navigation属性并尝试填充它们

但每当我检查它将为空

            using (var context = GetContext(false,true))
            {
                var queryable = context.Delegates.Where(i => i.ParentId == id);
                foreach (var entity in queryable)
                {
                    entity.FillNavigationProperties();
                    list.Add(WrapperFactory.Create(entity) as TU);
                }
                return new ObservableCollection<TU>(list);
            }

POCO示例

public class TempPOCO
{
      public virtual AnotherPCOCCLassTYpe NavigationProperty1{get;set;}
      public void FillNavigationProperties()
      {
            var tempcall = NavigationProperty1;
      }
}
