Message in Chinese (Simplified) (中文(简体))
“<var>X</var>”角色的对象无法自动添加到上下文中，因为它是使用 NoTracking 合并选项检索的。请在定义此关系之前，将该实体显式附加到 ObjectContext。
Unlocalized message
The object in the '<var>X</var>' role cannot be automatically added to the context because it was retrieved using the NoTracking merge option. Explicitly attach the entity to the ObjectContext before defining the relationship.
