The Expression team has reached an important milestone in this context and has delivered the first Community Technology Preview of Expression Web Designer (EWD).
EWD is a new professional design tool for creating HTML/CSS based web sites and applications. One of the great features is the deep support for web standards – something that is more important today than ever in the designer community. It also provides sophisticated CSS management and formatting with drag and drop features that will be exciting for designers.
And of course, there’s strong support for ASP.NET. You can kick the tires for yourself here.
