Breaking changes in VS2010 (Beta)

The (beta9 documentation for VS2010 is online, and therefor also the Breaking changes in VS2010 C/C++:

  • “auto” is now a keyword
  • “static_assert” is now a keyword
  • Lambda support excludes support for unquoted GUID in an IDL (it uses the same […] syntax)
  • Some “.NET-Exceptions” can now only be caught with __try __except
  • /GS checks might decrease performance
  • Project files are automatically converted to the new .vcxproj
  • CRT/MFC/ATL/OpenMP-DLLs no longer use fusion (huray!); it uses plan old dll-hell
  • Support for environmentvariable __MSVCRT_HEAP_SELECT was removed
  • New _ITERATOR_DEBUG_LEVEL macro (replaces _SECURE_SCL and _HAS_ITERATOR_DEBUGGING)
  • hash_map and hash_set are now in the std namespace (previously in stdext)
  • SafeInt is included

    Wow, did developer community feedback cause this?

    Finally. No more manifests and MSBuild support for vcproj’s.

    That alone is enough to make the switch worth it :)
