WPF 3.5 - XBAP with Firefox!
XAML browser applications (XBAPs) are now cross browser! See how in the .NET Framework 3.5, XBAPs can now run in Firefox, in addition to IE 6 and above! Navigate to an .xbap on the web running in Firefox, and the XBAP just works. Shell-execute or click on a hyperlink to a .xbap, and it will open in Firefox, if that is your default browser.
