During today's MSDN event in London I showed to two audiences this really great example of integrating ASP.NET Ajax and WPF/E: It integrates ASP.NET, Ajax, WPF/E and Web Services to provide a very compelling way of viewing albums brought down from Amazon's web service.
Great work by Dan and I hope to see more of this type of stuff appearing on t'internet - Amazon album viewer using WPF/E and ASP.NET Ajax
Another great thing about presenting in London was seeing a more diverse range of web developers from web 2.0 types, consumer web apps through to more normal enterprise/business web apps. And there was some cool ideas being banded about in the Q&A time for using WPF/E in production apps.
