27.5. Building a WPF Application using Only XAML

A typical WPF application will not be composed exclusively of code, as you did in this first example. Rather, your C# code files will be paired with a related XAML source file, and together they represent the entirety of a given Window or Application, as well as other class types we have not yet examined such as UserControl and Page.

This approach is termed the code file approach to building a WPF application, and you will make use of this technique extensively throughout the remainder of the books WPF coverage. However, before you do, the next example will illustrate how to build a WPF application using nothing but XAML files. While this "100% XAML" approach is not recommended, it will help you clearly understand how blobs of markup are transformed into a corresponding C# code base, and ultimately, a .NET assembly.
