WPF - My Next Big Thing
Having been playing with Silverlight for a while now on official projects, I'm now working full time on a WPF application for a client. This blog should now be more heavily investing in WPF content as I work more in this area than Silverlight now. I hope to blog pretty often regarding some of the cooler things WPF can do, the pitfalls you may come across and get some knowledge into the domain.
If you're into WPF at all, start having a look at the CommandManager that comes in .Net 3.0. Pretty neat stuff for separations of your logic and display and really helpful in what we're currently doing.
