UK Visual Basic MVP Ged has been taking a look at WPF this year. I spotted his post on WPF Basics: How To Play Sounds and Music in Windows Presentation Foundation a couple of weeks back and found it a clean, easy to follow example - that really tried to help others avoid some of those frustrations you typically run into when trying something new (Which I am running into lots at the moment as well!). He has several other WPF posts all worth a read if you are new to WPF development and his most recent post takes you to a shiny new article on Windows Forms and WPF Interop in which he creates a rich WPF list control. All good stuff.
