Windows Web Services API (WWSAPI) Now Available on R2, Windows 7, and Down-Level Platforms
WWSAPI is a native-code implementation of SOAP Web Services for both Windows client and server endpoints. WWSAPI provides core network communication and distributed computing functionality by supporting a sub-set of the WS-* protocols. A designer might choose to implement solutions using WWSAPI given the following requirements, for example:
- A native code only mandate
- Minimal library or component dependencies
- Minimal tolerance for endpoint service startup times
- Minimal runtime process working set
- Per process memory constraints
- Avoidance of native/managed interop scenarios
- Easy to WS-* enable a legacy native service or solution-domain library
Until now, the WWSAPI runtime library (i.e. "WebServices.dll") has only been available on beta Windows 7 (the client) and Windows Server 2008 R2 (the server). Developing for either client or server endpoints required the pre-release Windows 7 SDK to access the "WebServices.h" header file.
Now, WWSAPI has been back-ported to include support for XP, Server 2003, Vista, and Server 2008. WWSAPI is still not officially released and is made available as a beta version only.
