I would love to configure Visual Studio/ReSharper to run \"Code cleanup\" whenever I save a file.
A bonus would be to configure this only for C# files, as I sometime
In version 2020.2+ of R# there is now build in option to run cleanup on save:
Resharper Options > Code Editing > Code Cleanup > General
If you are on VS2012, and you can't use the macro solution, you could use AutoHotKey (or similar) to automate it, instead of using macros:
In AutoHotKey create a snippet that looks something like that:
^s::
Send, ^+c
Sleep, 300
Send, ^+s
return
