You may remember that I have written articles for the Windows API Code Pack (http://www.emoreau.com/Entries/Articles/2009/10/Windows-API-Code-Pack-for-Microsoft-Net-Framework--Part-1.aspx and http://www.emoreau.com/Entries/Articles/2009/11/Windows-API-Code-Pack-for-Microsoft-Net-Framework--Part-2.aspx) which is a free library to include Windows 7 capabilities into your own .Net Windows/WPF applications. Capabilities such as the JumpLists, icon overlays, thumbnails, libraries, power management, and more are easy to build using this library.

Parts of this library are now available to Silverlight developers who have application running Out-Of-Browser (OOB). This new library is available from the MSDN Code Gallery (http://code.msdn.microsoft.com/nesl) and is named “Native Extension for Microsoft Silverlight” (AKA NESL).
