You can also select Only changed parts of file to make sure that cleanup is applied to the code affected by your changes, and the rest of the code in the file is not modified.

If you choose to clean up only the changed parts of files, you can fine-tune this behavior with the following options:

• Perform full cleanup if partial cleanup is not possible — depending on this option, ReSharper will either clean up the whole file or skip the file if it is not possible to restrict the cleanup to the modified parts of the file.

• Allow cleanup on save for shared files — use this option to enable or disable partial cleanup in files that are included in the solution several times, such as files from shared projects.
