A new WPF Ribbon Control will be available for
download shortly after the release of WPF 4. It features skins for Windows 7
and Office, as well as all the standard Ribbon features that end-users are
familiar with, including tabs and groups, dynamic resizing, quick access
toolbar, application menu, contextual tabs, key tips, and more.
The WPF Ribbon will be fully extensible to meet changing
guidelines for future releases. A CTP with a limited feature set is available
