In this chapter and the preceding two chapters, you’ve learned about all the major ways that WPF builds on top of the foundation of the .NET Framework. The WPF team could have exposed its features via typical .NET APIs, as in Windows Forms, and still have created an interesting technology. Instead, the team added several fundamental concepts that enable a wide range of features to be exposed in a way that can provide great productivity for developers and designers.
Indeed, when you focus on these core concepts, as this chapter does, you can see that the landscape isn’t quite as simple as it used to be: There are multiple types of properties, multiple trees, and multiple ways of achieving the same results (such as writing declarative versus procedural code)! Hopefully you can now appreciate some of the value of these new mechanisms. Throughout the rest of the book, these concepts generally fade into the background as we focus on accomplishing specific development tasks.
