One thing that has been nagging me for some time is that I have not yet upgraded my skill set to include many of the .NET 3.X technologies. Windows Presentation Foundation (WPF) and Windows Workflow Foundation (WWF) both look quite interesting, but I just cannot seem to justify taking the time to learn either technology. WPF seems like it would be a complete replacement of the Windows Forms knowledge that I have built up over the years, and I cannot seem to find a good reason to use WWF in any applications.

Also, I don’t hear many real-world developers talking about these technologies. Am I missing something here? Please take this quick poll to let me know if you’re using the .NET 3.X technologies.
