Breaking Changes in Visual C++ .NET 2003

The Visual C++ compiler has significantly increased its conformance with the C++ standard in the Visual Studio .NET 2003 release. With this conformance comes a number of breaking changes. Many of those changes now result in compiler errors, where no compiler errors were given in previous releases. However, there are also a number of silent, or runtime errors, which are described in this section.

A nonconformance related breaking change is that just-in time debugging for /clr images will not work unless you either add DebuggableAttribute or use a configuration (.ini) file; see Making an Image Easier to Debug for more information.

For remaining conformance issues, see Standard Compliance Issues in Visual C++.
