I've been using WinFX SDK on WinXP SP2, I have installed the longhorn build 7074, the problem Im having that the my .xaml files are not working!
I tried to refer to another book rather than the SDK help, i found almost totally diffrent names of the tags and file structure such as project files.
I tried to use the book examples but they won't run either! Guys I'm stuck! any hints?

Book: Introducing Microsoft WinFX, Brent Rector,Microsoft Press.
