We are excited to introduce the alpha version of Windows Live ID for client applications!
The Windows Live ID Client 1.0 SDK provides a managed API for Windows Live sign-in. Included in the release is a sample application together with its source code so that you can build your own client applications.

Please note that the use of the Windows Live ID Client 1.0 SDK is governed by our license agreement.

Benefits:

• No need to worry about the technical details of authentication! The Windows Live ID authentication service manages this process for you.
• Don�t bother worrying about how to store and retrieve user account information! The Windows Live ID service uses the same functionality as Messenger to cache the user name and/or password for use in later user sign-ins.
• By enabling Windows Live accounts to directly sign in to your site, any of the hundreds of millions of users who have a Windows Live ID can become a user of your site.
