Sams Teach Yourself Visual C++.NET in 24 Hours

In this hour, you learned how to create and use an ATL Web Service. Although the process is somewhat different in ATL, the resulting Web Service is equally flexible for use as demonstrated with the test application you created. ATL Web Services have the advantage of being able to use unmanaged code efficiently and can even mix MFC code if needed. Third-party libraries don't have to be wrapped by managed class wrappers as they do in a .NET Web Service.
