Windows Live Messenger Library 2.0 is released

The Windows Live Messenger Library is (WLML) a client-side library for building presence-enabled instant messaging web applications hosted in any domain that site visitors can use to interact with each other and Windows Live Messenger users. WLML is written in C# and compiled into JavaScript using Script#; applications can be written either in C# (with Script#) or JavaScript. WLML 2.0 has been released: it is backward compatible with WLML 1.0 and the version 1.0 API is still available. The new version (documentation) contains the following changes:

  • Sorted contact collections: New OnlineContacts and OfflineContacts collections list contacts in sorted order to make it easier for applications to show sorted contact lists.
  • Contact display picture links: Contact display picture links are now returned but with respect user privacy, there is some special handling required to use them in applications.
  • Customization for the Sign-In Control: color schemes can now be defined for the Sign-In Control.
  • A new URL for loading the library: Library files are now content distributed globally; applications should see improved library load time.
  • Hosted static images for status icons and Messenger logos: GIF and PNG static images for applications to use for displaying user status are now being hosted.
  • URL strings for Messenger resources: The library returns a set of market-specific URLs for applications to display links to required Microsoft pages such as the privacy statement. This is to enable applications to move the Sign-In Control out of view when it is not needed.
  • Sign-In Control returns extended authentication results: The Sign-in Control has been updated to return more detailed information about user authentication results.
