This chapter has a mix of topics that will be covered on the exam, and these four topics do not directly relate to each other. The first three topics cover features that can be used to examine, customize, or generate C# code, while the last topic explains how to write shorthand syntax for your existing methods. It is especially important to understand the concept of lambda expressions because not only will you see them used extensively in Chapter 10, “Working with Language Integrated Query (LINQ),” but you will see questions on the test that use lambda expressions and you could be asked what the result of the expression would be.
