The Microsoft Platform Evangelism team released a very nice technology demo product to show all the new cool technologies Microsoft just released or is going to release during that year.
The demo utilizes several technologies including: IIS7, ASP.NET Ajax Extensions, Linq, Windows Communication Foundation, Windows Workflow Foundation, Windows Presentation Foundation, Windows Powershell, and the .NET Compact Framework.
The also build a web site DinnerNow.net, that will contain a working demo, and will host videos showing the features of the "product". At the moment of writing there is just one video, that explains the end-user experience, from when the user browses an Ajax based website, register and buy using a CardSpace identity, and then tracks his order using a Vista Gadget.
Looking forward to see the second episode.
