With Windows Web Services, you can create applications that communicate easily with a local computer or a remote Web service. Windows Web Services is a native-code implementation of SOAP and provides core network communication by supporting a broad set of the Web services (WS) family of protocols. Windows Web Services is a peer to Windows Communication Foundation (WCF – managed-code Web services), and provides a high-performance subset of WCF functionality.
Watch Yochay Kiriaty, Windows 7 Technical Evangelist, and Windows Web Services API PM Nikola Dudar as we explain the Windows native Web Services APIs, and why Microsoft created a new set of Web Services APIs when we have WCF. For more technical content on Windows 7 and few cool code samples, go to the Windows 7 Blog for Developers.
