Thanks for the report. This issue has been fixed in the MFC header file for the RTM release of Visual Studio 11.

Yet more info:

It looks like stdafx.h is different in MyProject (an existing project in VS11 Beta), compared to a new project created using RC 2012. In the former, the Windows versions are set in stdafx.h itself, while in the latter, a file targetver.h is included.

Additional info:
Build of project fails, with error "can't open tmschema.h" from afxwin.h. Problem stems from

#if ((NTDDI_VERSION >= NTDDI_LONGHORN || defined(__VSSYM32_H__)) && !defined(SCHEMA_VERIFY_VSSYM32))
#include <vssym32.h>
#include <tmschema.h>
#endif    // (_WIN32_WINNT >= 0x501)

and defining __VSSYM32_H__ in PROJECT / MyProject Properties... / Configuration Properties / C/C++ / Preprocessor / Preprocessor Definitions makes the error go away. Apparently either the test, or the version numbers are incorrect.
