Used WPF for a while many years ago (so I'm not up to date on the latest), but I was frustrated by so many oddities and gotchas innate to the system. There were some great demos that made me think I had a handle on how it worked, but then I immediately hit a wall trying to implement a real product. If it weren't for Stack Overflow, and all the people asking the same WPF WTF questions I had, I would have never had achieved any success.
