Connecting native C/C++ code and Web Services using WWSAPI

On this page, you can find links to all resources available for connecting C and C++ code and web services.  Windows Web Services API (WWSAPI) is a unified framework for building SOAP based web services and clients to them. It provides the support for the core WS-* and .NET-* protocols around building SOAP services. You can use WWSAPI in components and applications that fall into one of the following categories:

·         Native code mandate and taking dependency on .Net Framework is not acceptable

·         Require high throughput on the server side

·         Require very small working set during runtime

·         Minimal dependencies can be used

·         Need for minimal startup time

·         Memory constrained environments

WWSAPI is available out of the box on Windows 7 and Windows Server 2008 R2. To get development tools, webservices.h header and webservices.lib library, you need to install Windows SDK for Windows 7.

Below are groups of links to resources available to help you to start using WWSAPI in your product.
