Specifically,
https://github.com/microsoft/win32metadata noting that this is distinct from any historical project to define the Windows APIs.
Seems like a good idea to me, particularly since over the last few days one forum thread has been debating Pascal-style var vs MS-style Hungarian Notation. However, I note that it applies to Win-32, and find myself wondering to what extent it also applies to Win-64: if it drives a wedge between attempts to keep the existing Windows API definitions in step it could be counterproductive (is that an evil gurgle from Steve Ballmer I hear in the distance? :-)
