Due to the inherent flaw in English, I always use Chinese when enumerating, so that I don’t need to read the comments to know the meaning of the enumeration. Today I saw the blog post
Using attributes instead of directly using Chinese as attributes. The part is specially excerpted for future use

Replace the out parameter in the original text with the return element Group, since the project is developed in vs2015, it cannot use c#7.0 features, otherwise it would be better to use the value tuple in 7.0. Performance and display friendliness will be improved.
