To accompany our book, you'll find a number of code samples that map to specific chapters. This code should be used for learning purposes only. That is, it is not production-quality code. 

That said, you'll find sample code for each chapter except for Chapter 8, which is less of a walkthrough chapter and more of 'here's what you can do now that you've read this book' chapter. 

Included within the code samples, then, are:

Chapter 1: Introduction to Silverlight
Chapter 2: Your First Silverlight and SharePoint Integration
Chapter 3: Creating Custom Field Types
Chapter 4: Branding a SharePoint Site with Silverlight
Chapter 5: Custom Web Parts
Chapter 6: Advanced Custom Web Parts
Chapter 7: Data Connectivity

Also make sure that if you do use the source code, you look for any comments in the code or walk through the chapters to understand deployment details. For example, some of the code uses custom services, which require you to deploy the services to your environment before your SharePoint site can consume the Silverlight applications. 

Happy coding!
