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, organised into “items”: short vignettes offering careful advice, concise technical explanations, and illuminating examples.
In More Effective C#, Second Edition, world-renowned .NET expert Bill Wagner identifies and illuminates 50 intermediate-to-advanced techniques for writing exceptionally robust and well-performing C# 7.0 code. Reflecting the growing sophistication of the C# language and its development community, Wagner presents powerful new solutions to problems you’re likely to encounter every day.
Through three editions of Effective C#, Wagner’s clear explanations, expert tips, and realistic code examples have proven invaluable to hundreds of thousands of developers. With the publication of this title, Effective C#, Third Edition, and More Effective C#, Second Edition, have been completely reorganized to provide clear explanations, expert tips, and realistic code examples in a cohesive package for modern C#. More Effective C#, Second Edition, brings the same proven approach to the new features in C# 7.0, helping you perform familiar tasks more efficiently and effectively.
Drawing on his unsurpassed C# experience and key role on global C# standards committees, Wagner addresses object-oriented, functional, and service-oriented approaches to managing data with C#; better ways to express your intent to users and other programmers; and new opportunities to leverage powerful asynchronous and dynamic programming techniques.
