The Windows Live ID Web Authentication SDK describes a platform-independent interface for implementing Windows Live ID sign-in on Web sites of all kinds. This release includes a sample application for each of six different programming languages: ASP.NET, Java, Perl, PHP, Python, and Ruby. For each language there is a function library that you can use to extend the sample.
The SDK consists of the samples and libraries available on this page together with the SDK documentation. For a link to the documentation on MSDN®, see Related Resources later on this page.
