因为运行时不能区分List和List(运行时都是List)，用泛型类型参数标识类型的变量的构造就成了问题。

Because the runtime cannot tell a List from a List (at runtime, they're both just Lists), constructing variables whose type is identified by a generic type parameter is problematic.

实体键属性的值必须在运行时唯一标识实体集中的实体类型实例。

The values of entity key properties must uniquely identify an entity type instance within an entity set at run time.
