# How to reformat all C# files in a solution, in Visual Studio 2012.
#
# Open Tools->Library Package Manager->Package Manager Console, and run the
# command below. At the end, all documents will be open in the IDE. (Low-RAM
# machines will have problems with large solutions.) Changed files will be
# modified in the IDE, and not saved to disk. You can SaveAll, then Close All
# if you're ready.
#
# VS2012 removed the VB-like macro language that existed in previous version of
# Visual Studio. However, the underlying DTE interface is still there, and you
# can reach it via PowerShell, in the Package Manager Console
#
# The weird GUID passed to [ProjectItem.Open](http://msdn.microsoft.com/en-us/library/envdte.projectitem.open.aspx)
# is [Constants.vsViewKindCode](http://msdn.microsoft.com/en-us/library/envdte.constants.vsviewkindcode.aspx).
#
# Normally I'd split this in to multiple lines, but the Package Manager Console
# doesn't support line continuation.
