VS2013 has added auto-formatting for C++. My personal opinion on auto-formatting is that it\'s ultimately harmful for developers but I have to accept not everyone agrees. Wh
I also had this problem and unchecking all the checkboxes in the formatting options did not help.
It turned out that this was caused by an option in the plugin “Visual Assist X” from Whole Tomato Software.
In my case this problem could be solved by going to “Visual Assist Options”-->”Corrections” and unchecking the Checkbox “Format after paste”.
