Developers familiar with conventional COM programming using Visual Studio® 6.0 and ATL 3.0 will find an extraordinarily empowering suite of tools and classes in the new ATL 7.0 library that comes with Visual Studio .NET. The classes that support such Web application development as building XML Web Services are collectively termed ATL Server. This article will explain how the C++ programmer can use the facilities available in ATL Server to develop high-performance Web Services quickly."
