Yesterday Lebdev held the Visual Studio.NET 2008 and Windows Server 2008 Community launch. We had some great demos and presentations.
Maral Topalian did a great presentation on Windows Server 2008.
Bilal Haidar did an awesome demo showing the new features of Visual Studio.NET 2008, ASP.NET 3.5, ASP.NET AJAX and Linq. You can download the demo code from his blog, its worth checking.
I came last in this event, showing a very simple demo using SilverLight 2.0, ADO.NET Entity Framework and ADO.NET Data services. I then created a WPF application by simply copy/pasting the code I used to create the Silverlight application into the WPF application. You can download the demo project here.
