GigaplexNZ writes: Earlier this year a bug was filed against the developer preview of the next version of Visual Studio complaining that applications built with it are incompatible with Windows XP. Pat Brenner from Microsoft Visual C++ Libraries Development issued a response: "Thanks for the report. This behavior is by design in MFC and CRT for Visual Studio vNext. The minimum supported operating systems are Windows Server 2008 SP2 and Windows Vista. Windows XP is not a supported operating system for the release (design-time or run-time)." Can Microsoft seriously be considering preventing early adopters of the next version of Visual Studio from supporting a large portion of their existing customer base?
