You can use this page to adjust line wrapping settings. Options in the Preserve Existing Formatting section are applied when ReSharper reformats existing code while the three remaining sections contain options that take effect when you type new code. Use spin boxes, drop-down lists and check boxes to adjust settings and the preview pane in the lower part of the tab to observe effects.
ReSharper's settings are saved in settings layers that enable you to have different settings for different solutions as well as to share your settings with your team. To learn more, study the Managing and Sharing Options section.
