Windows API Code Pack for .NET

Hold the phone—MS has released the Windows API Code Pack for Microsoft .NET Framework, a source code library for accessing a bunch of Windows features that aren't directly supported by .NET. It concentrates on new Windows 7 features, but there's support for some Vista APIs as well—including task dialogs.

Some of the supported APIs:

• Win7 libraries
• Known folders
• Task dialogs
• Vista and Win7 common dialogs
• Win7 taskbar jump lists, icon overlays, and progress bars

I haven't done any work with this yet, but it certainly looks promising. The code pack home page is in the MSDN Code Gallery, and the download page is here. Enjoy.
