The chapter 1 app (like almost every app in the book) uses a Settings class to interact with isolated storage. This way, it can remember values the next time the app runs. In the code download for the book, the project includes the necessary Settings.cs class which makes this error go away. The code for this class is also included in the book in Chapter 20, when the topic of isolated storage is discussed.

So you’ve got two options:

1.Copy Settings.cs from the Chapter 1 code download and include it in your project.

2.Create a new Settings.cs file in your project and type in the Settings.cs code from Chapter 20.
There is a bullet point in Chapter 1 that attempts to explain the situation, but I realize that it is too confusing.
