Did you notice the small broom icon at the bottom of your code editor window in Visual Studio?
This is the Code Cleanup button. It allows you to apply code styles from an EditorConfig file or from the Code Style options page. (The .editorconfig takes precedence).
To configure the exact Code Cleanup actions, you can click the expander arrow next to the code cleanup broom icon and then choose Configure Code Cleanup.
After you've configured code cleanup, you can either click on the broom icon or press Ctrl+K, Ctrl+E to run code cleanup.
