Message in Chinese (Simplified) (中文(简体))
不能向包含类型“X”的实例的集合添加类型“<var>Type Name</var>”的入口。当其他类型的现有入口具有相同标识值，或在一个查询中将同一个实体投影到两个不同的类型时，可能会发生这种情况。
Unlocalized message
An entry of type '<var>Type Name</var>' cannot be added to a collection that contains instances of type 'X'. This may occur when an existing entry of a different type has the same identity value or when the same entity is projected into two different types in a single query.
