Accessing UDDI API and Microsoft API Extensions Interfaces

UDDI Services supports the UDDI version 1.0 and 2.0 API specifications, as well as an extensions API for browsing categorization schemes.

It is recommended that you use the Microsoft® UDDI .NET Software Development Kit (SDK) to access these interfaces as it provides a superior programming experience over using the proxies generated directly from the Web Service Description Language (WSDL) files. To download the SDK and access additional UDDI information, see the UDDI Services Web site on the Microsoft Web site.

UDDI WSDL files are available on the UDDI specification Web site.
Microsoft API Extensions WSDL files are available on the Microsoft UDDI Business Registry Web site.
