如何在同一解决方案中为多个项目使用 app.config？

Question

I have 2 projects in single solution and both should be using common app.config file. By doing web search, i came across solution => Add config using "Add as a link" option. But this option is not available in visual studio 2019.

Can someone help how to achieve this?

1. Add New Solution Folder (menu item on the solution node of the Solution Explorer) called "Shared".
2. Add/create an app.config file to the folder.
3. For each project that needs using the app.config file, Add Existing Item -> navigate to the file location -> select the file -> press down-pointing triangle on the Add button of the item/file selection dialog and select Add as Link .
