Just attended the local .NET Users Group here in Winston Salem/Greensboro where Brian Hitney, a Developer Evangelist from Microsoft presented on .NET 3.0 which seems to be essentially add ons for .NET 2.0. The WPF and XAML topics were pretty interesting. There are some WPF controls already out there, including a Wizard control from ActiPro (http://www.actiprosoftware.com/Products/DotNet/WPF/Wizard/Default.aspx). There are also some WPF and XAML controls out there on http://www.codeplex.com. The WCF seems like it is going to be a good replacement for doing SOA, combining web services with more integrated security, better transaction handling, and providing more reliable communications. I'm still trying to determine how I might use WF (Workflow) but I think it can change how some processes are modeled. The CardSpace features seem to be something that I'm still a little lost as to when I would use it or if I even want to use it. Microsoft should make it so I can log into MSDN using CardSpace and then it really would be useful :)
If I come across new WPF/XAML controls, I'll post them in this space.
Brian did show the New York Times WPF Reader application (http://windowsvistablog.com/tags/New+York+Times+Reader/WPF/default.aspx) and it seems like applications like this could really be killer type apps to show off what WPF and WPF/E can do.
