A perfectly innocent line of code
But in the eyes of Style Cop it is evil. And justifiably so. This is a simple example but perfect spacing, removing and sorting usings and other small simple tasks start to accumulate. These are all still important things you should do for others and your own future convenience.
However these are things you would rather have your code editor do so you can focus on solving the actual problem you are trying to solve. Enter CodeMaid (http://www.codemaid.net/) .
It does these and more for you on file save. So your code looks the way code should look everytime.
If you use stylecop (which you should) you need a code maid.
