Using the last custom class that you created as part of your job, modify it so that it can be serialized. Then write an application to serialize and deserialize it using BinaryFormatter. Examine the serialized data. Then modify the application to use SoapFormatter. Examine the serialized data. Examine the class that you used in Practice 1 and, if possible, identify a member that does not need to be serialized. Modify your class so that the member will not be serialized but will be defined automatically upon deserialization.

Control the Serialization of an Object into XML Format by Using the System.Xml.Serialization Namespace
For this task, you should complete all three practices to gain experience using XML serialization with real-world classes and schema.
Practice 1
Write an application that uses XML serialization to serialize and deserialize the last class that you created as part of your job. Examine the class that you used in Practice 1 and, if possible, identify a member that does not need to be serialized. Use an attribute to modify your class so that the member will not be serialized.
Practice 2
Practice 3
Find an XML schema on the Internet and create a class that, when serialized, conforms to that XML schema. Create the class using two different techniques: manually and with Xsd.exe.
Implement Custom Serialization Formatting by Using the Serialization Formatter Classes
For this task, you should complete at least Practices 1 and 2. If you want in-depth knowledge of the serialization process, complete Practice 3 as well.
Practice 1
Using the last custom class that you created as part of your job, modify it so that it implements ISerializable and can be successfully serialized and deserialized. Examine the members to determine whether you can optimize serialization by omitting calculated values. Create a class that provides methods for all four BinaryFormatter serialization events.
Practice 2
5 Review
Implement the IFormatter interface to create a custom formatter. Use it during serialization and deserialization to understand the formatter s role in serialization.
Practice 3
Take a Practice Test
The practice tests on this book s companion CD offer many options. For example, you can test yourself on just one exam objective, or you can test yourself on all the 70-536 certification exam content. You can set up the test so that it closely simulates the experience of taking a certification exam, or you can set it up in study mode so that you can look at the correct answers and explanations after you answer each question.

Graphics
You can use graphics to enhance the user interface of your applications, generate graphical charts and reports, and edit or create images. The .NET Framework includes tools that allow you to draw lines, shapes, patterns, and text. This chapter discusses how to create graphics and images using the classes in the System.Drawing namespace.
NOTE
WPF Graphics
.NET Framework versions 3.0 and later include Windows Presentation Foundation (WPF), which provides robust graphics capabilities beyond those provided by the System.Drawing namespace. However, the 70-536 certification exam covers only the System.Drawing namespace. Therefore, for the purpose of this exam, you should disregard the WPF graphics capabilities.
Exam objectives in this chapter:
Enhance the user interface of a .NET Framework application by using the Sysem.Drawing namespace Enhance the user interface of a .NET Framework application by using brushes, pens, colors, and fonts Enhance the user interface of a .NET Framework application by using graphics, images, bitmaps, and icons Enhance the user interface of a .NET Framework application by using shapes and sizes
