C# odata v4无法在另一个复杂类型中选择复杂类型的属性（使用扩展）

我有一个模型，上面有项目（根），然后是复杂类型（制造），嵌入了另一个复杂类型（位置，下面名为工厂）

在扩大生产时，一切都按预期进行：

https://localhost/Inextrace/Items('ABC123456789')?$select=Code&$expand=Manufacturing($select=Factory)

但是，当我尝试只选择复杂类型位置（Factory）的一个属性时，它表示不支持该属性。有什么解决办法来实现这一点吗

https://localhost/Inextrace/Items('ABC123456789')?$select=Code&$expand=Manufacturing($select=Factory/Code)

响应：

    }
  }
}

有没有办法只选择工厂的某些领域

我正在使用C#.Net和以下版本的nuget软件包：

• Microsoft.AspNet.OData v5.8.0
• Microsoft.OData.Code v6.14.0
• Microsoft.AspNet.WebApi v5.2.3
