Target Audience for This Book
My challenge with this book was how to keep advanced developers awake while not abandoning beginners by using words such as assembly, link, chain, thread, and fusion, as though the topic was more appropriate for blacksmiths than for programmers. This book’s primary audience is experienced developers looking to add another language to their quiver. However, I have carefully assembled this book to provide significant value to developers at all levels.

• Beginners: If you are new to programming, this book serves as a resource to help transition you from an entry-level programmer to a C# developer, comfortable with any C# programming task that’s thrown your way. This book not only teaches you syntax, but also trains you in good programming practices that will serve you throughout your programming career.

• Structured programmers: Just as it’s best to learn a foreign language through immersion, learning a computer language is most effective when you begin using it before you know all the intricacies. In this vein, this book begins with a tutorial that will be comfortable for those familiar with structured programming, and by the end of Chapter 4, developers in this category should feel at home writing basic control flow programs. However, the key to excellence for C# developers is not memorizing syntax. To transition from simple programs to enterprise development, the C# developer must think natively in terms of objects and their relationships. To this end, Chapter 5’s Beginner Topics introduce classes and object-oriented development. The role of historically structured programming languages such as C, COBOL, and FORTRAN is still significant but shrinking, so it behooves software engineers to become familiar with object-oriented development. C# is an ideal language for making this transition because it was
designed with object-oriented development as one of its core tenets.

• Object-based and object-oriented developers: C++ and Java programmers, and many experienced Visual Basic programmers, fall into this category. Many of you are already completely comfortable with semicolons and curly braces. A brief glance at the code in Chapter 1 reveals that at its core, C# is similar to the C and C++ style languages that you already know.

• C# professionals: For those already versed in C#, this book provides a convenient reference for less frequently encountered syntax. Furthermore, it provides answers to language details and subtleties seldom addressed. Most important, it presents the guidelines and patterns for programming robust and maintainable code. This book also aids in the task of teaching C# to others. With the emergence of C# 3.0, some of the most prominent enhancements are:

– Implicitly typed variables (see Chapter 2)
– Extension methods (see Chapter 5)
– Partial methods (see Chapter 5)
– Lambda expressions (see Chapter 12)
– Expression trees (see Chapter 12)
– Anonymous types (see Chapter 14)
– Standard query operators (see Chapter 14)
– Query expressions (see Chapter 15)

• These topics are covered in detail for those who are not already familiar with them. Also pertinent to advanced C# development is the subject of pointers, in Chapter 21. Even experienced C# developers often do not understand this topic well.

Features of This Book
Essential C# 3.0 is a language book that adheres to the core C# Language 3.0 Specification. To help you understand the various C# constructs, it provides numerous examples demonstrating each feature. Accompanying each concept are guidelines and best practices, ensuring that code compiles, avoids likely pitfalls, and achieves maximum maintainability. To improve readability, code is specially formatted and chapters are outlined using mind maps.
