asp.net 核心 3.1 web 应用程序中未显示的代码参考

Question

my codes in asp.net core 3.1 is not showing references at all, have created a book model class, and was expecting my code to looks like something like this,

0 refrences
public class book()
{

}

but it was only

public class book()

and these is as been going on everywhere in the scope of the project i created, i created two new project entirely to check if its the app but am stil not getting it.

when i tried it without using refrences, i later have errors inheriting class and some inbuilt functions. Asp.net core 3.1 web application using. visual studio 2019 16.6.2 latest.

Answer 1

Remove() suffix in book class because it denotes method.

public class book
{

}

Answer 2

1. goto Tools in visual studio and select options
2. you can search for codelens in the search box and check the checkbox
