Using Directives Sorted in Wrong Order

Question

I'm using the Power Commands extension with Visual Studio 2012. I have the option checked to remove and sort usings on save. The problem is that the System.Xxx directives are being sorted last, and that's causing a style analysis error:

SA1208: System using directives must be placed before all other using directives.

Before save:

using System;
using System.Diagnostics.CodeAnalysis;
using Foo;

After save:

using Foo;
using System;
using System.Diagnostics.CodeAnalysis;

This worked correctly (System.Xxx first) with VS 2010. Anyone know how to correct this?

Note: Even if it didn't cause an SA error, I'd still prefer the system directives to be first.

Answer 1

Goto the "Quick Launch" (Ctrl+Q) and type "using" and press Enter .

Then change the following setting:

It's an annoying default setting, I have no idea why Microsoft chose that, it goes against all previous standards that I've ever seen.

EDIT: Thanks to Oskar we have a reason :

The reason for the change in default behavior is due to the fact that Windows App Store applications prefer to have 'Windows. ' at the top of the file rather than 'System. '
