Editor

• Visual Studio can now automatically save code documents whenever the application loses focus. This feature can be accessed via Tools > Options > Environment > Document. If the "Autosave" option is checked, Visual Studio will attempt to save all dirty code documents whenever the Visual Studio application loses focus (e.g. when switching to another application in Windows).
• The Code Cleanup feature can now be configured to be run whenever a file is explicitly saved. In Tools > Options under Text Editor > Code Cleanup, a new option allows users to enable the Code Cleanup on explicit save as well as to select the profile to run. Note that this option will not cause Code Cleanup to be run on autosave.
