Why do some C# applications have an app.config file and others do not? Both of these solutions were initialized as Visual C# Windows Form Applications.
This one I created in Visual Studio Community version:
This screen capture bit is from a youtube tutorial. I followed along with the instructor in the video and He created it with a menu selection as a Visual C# -> Windows Form Application.

Hello William,
Thank you for reaching out to us.
The project in the first image is targeting .Net Core while the project in the second image is targeting .Net Framework. With the release of MS .Net Core projects, the App.config file is not included by default when a WinForms application is created. However, that does not mean that you can't add it afterward. When you start to create a project you can observe two templates.
The first template targets .Net Core while the second one will target .Net Framework. When you choose the first template you can see the target framework drop-downs that it does not contain .Net Framework versions.
If we choose .Net 7 for example, you can click on the Add New Item from the Project context menu.
Then you manually add the Application Configuration File (App.config) file.
I hope that you find this information helpful.
