Quartz is the codename for an web development IDE, part of the Expression suite, that is targeted at web designers/developers. It’s undeniably the best implementation of web development environment out of Microsoft ever. It blows VS.NET off the face of the Earth with it’s support for designing web sites with respect to standards technologies (CSS, [X|D]HTML, XSLT, etc.). It also fully supports ASP.NET controls and master page design. As a VS.NET user I’m already jealous.
This product came as somewhat of a surprise (to me at least), but it’s arguably the most immediately useful product I’ve seen coming out of the PDC so far. My only question is: How do I sign up for or where do I download the Beta!? 🙂
