App.Config stop creating

If the selected answer doesn't work for you, i.e. App.Config file still keeps getting created, then you likely have the Auto-generate binding redirects selected in your Project -> Properties.

In this case, you can uncheck and save this setting, and then remove the app.config file ans save the project.

This solves the problem.

if you are not using it at all, just remove it from your project and it won't get created anymore.
