I tell you this XPS support is still a joke. Still no one at MS has done anything to improve the situation. I trust the issue with not being able to open an XPS file out of Windows Live Mail (desktop app) is an issue in the Windows Live Mail team, but come on… why wouldn’t the XPS team make a call? The Windows Live Mail support for XPS is a joke! Why not integrate the XPS rendering directly into the Mail app so it comes up in the email with live previews. Maybe that’s a stretch for a company that so completely doesn’t give a care about the technology they invented, but how about at least making it work within Windows Live Mail as well as PDF or any other document format supported? This is truly a joke.
