So I'm here at TechEd 2007 enjoying the humidity of Orlando in June. I delivered a Precon on WCF and WF on Sunday with Jon Flanders which was a blast. Mark Smith who writes our WPF course asked me to check out what I could find out about Acropolis - a new framework for creating WPF applications. The Acropolis website went live on Monday and so I wandered over to the boothe to see what I could find out. It came as quite a surprise that Dave Hill, who i used to work with in the UK about 8 years ago, was on the stall. Dave is the architect on Acropolis - its a small world. I had lunch with Dave and it looks like they have some interesting ideas for helping to enforce separation between the presentation layer and business funtionality in an application and it is all expressed declaratively in XAML. If you're building smart clients in WPF its definitely worth keeping an eye on.
