The following compiler, linker, other build tools, and C++ language features are new for Visual C++ .NET 2003.

• Compiler
• Visual C++ Attributes
• Linker
• Preprocessor
• MASM

Compiler

• Information on how to run a Managed Extensions for C++ application built with the current version's compiler on a previous version of the runtime; see Running a Managed Extensions for C++ Application on a Previous Version's Runtime.
• Managed Extensions for C++ Frequently Asked Questions.
• A walkthrough has been added showing how to port an existing, native application to use Managed Extensions for C++: Walkthrough: Porting an Existing Native C++ Application to Interoperate with .NET Framework Components
• You can now create a delegate on a method of a value type.
• The compiler's conformance with the C++ standard has been significantly enhanced for Visual C++ .NET 2003. See Standard Compliance Issues in Visual C++ for more information. See Breaking Changes in the Visual C++ Compiler for information on where your upgraded Visual C++ applications may no longer compile because of enhanced conformance.
• /arch compiler option is added.
• /Gf is deprecated and will be removed in the next version of Visual C++.
• /G7 compiler option is added.
• The /GS compiler option has been enhanced to help protect local variables from direct buffer overruns.
• The /noBool compiler option has been removed. The compiler now allows bool to appear only as a keyword (and not an identifier) in a C++ source code file.
• The long long type is now available as a typedef of __int64. See Fundamental Types for more information. Note that there is not yet support for long long in the CRT.
• The /Zm compiler option now specifies the precompiled header memory allocation limit.
• _InterlockedCompareExchange intrinsic now documented.
• _InterlockedDecrement intrinsic now documented.
• _InterlockedExchange intrinsic now documented.
• _InterlockedExchangeAdd intrinsic now documented.
• _InterlockedIncrement intrinsic now documented.
• _ReadWriteBarrier intrinsic added.

Visual C++ Attributes

• implements attribute is now documented.

Linker

The following linker options have been added:

• /ASSEMBLYDEBUG
• /ASSEMBLYLINKRESOURCE
• /DELAYSIGN
• /KEYFILE
• /KEYCONTAINER
• /SAFESEH

Preprocessor

• The _STATIC_CPPLIB symbol is now documented for use with /MD.
• The _CPPLIB_VER symbol is now documented; see Predefined Macros for more information.
• The #import directive now has the following attributes documented:
  • auto_search
  • auto_rename
  • no_search_namespace
  • rename_search_namespace
  • tlbid
