Written for students with a strong basic understanding of C#, Bill Wagner’s More Effective C# will help them become outstanding programmers. Fully up-to-date, it introduces fifty intermediate-to-advanced-level techniques for writing highly-efficient and robust C# software. Packed with new techniques and code updated for the language’s newest capabilities, it follows the same format as Wagner’s best-selling Effective C#: clear, practical explanations, expert tips, and plenty of realistic code samples.

Drawing on his unsurpassed C# experience, Wagner helps experienced C# developers choose the most effective solution when multiple options exist, and develop code that’s easier to understand, maintain, and improve. Wagner also uncovers practices that compromise performance or reliability and shows exactly how to avoid them. Each section contains specific, actionable guidelines, organized into “items”: short vignettes offering careful advice, concise technical explanations, and illuminating examples.
