I've been doing quite a bit of WPF (Windows Presentation Foundation) experimenting recently, on a project that will hopefully turn into another commercial product for BinaryComponents.

It's in very early stages as yet, which is why I'm showing tiny screenshots instead of full-size ones. (You can't see so many rough edges that way). All of the XAML, both content and style, is hand-coded by the way - learning Expression Blend is a job for the future. Data access is using LINQ, of course.

I think I'm finally getting the hang of the WPF "way" - it's taking me a while to untrain myself from the WinForms modes of thought. If anyone's starting a new desktop application and can't decide whether to learn WPF or stick with WinForms - my advice is definitely to go for WPF - once it clicks, you won't want to go back. (Of course, whether you want to develop desktop applications is another question entirely).
