Using Web Services on Devices
The Microsoft Web Services on Devices API (WSDAPI) supports the implementation of client-controlled devices and services, and device hosts conforming to the Devices Profile for Web Services (DPWS). WSDAPI may be used for the development of both client and server (device) implementations.
Whenever possible, use WSDAPI to create a Windows-based WSD client or device host application. Using WSDAPI reduces the complexity of development and saves time. For more information, see WSD Application Development on Windows and WSDAPI Development Tools.
You can also create WSD devices that do not run Windows and are interoperable with Windows-based WSD clients and device hosts. These devices must meet specific requirements to maintain interoperability. For more information, see WSD Device Development.
