Essential C# 7.0 is a well-organized, no-fluff guide to C# 7.0 for programmers at all levels of experience. Reflecting C# 7.0 features and modern programming patterns, it will help you write code that’s simple, powerful, robust, secure, and maintainable.

Author Mark Michaelis is a world-class C# expert: a long-time Microsoft MVP and Regional Director who also has served on Microsoft’s C# design review team. He presents a comprehensive tutorial and reference for the entire language, including expert coverage of key C# 7.0 enhancements, C# 7.0’s use with .NET Core/.NET Standard, and cross-platform compilation. He illustrates key C# 7.0 constructs with succinct examples, and presents best-practice coding guidelines. To help you maintain existing code, separate indexes provide version-specific answers for C# 4.0, 5.0, 6.0, and 7.0, and visual icons show when each language innovation was introduced.

  • Make the most of C# 7.0 enhancements, including tuples, deconstructors, pattern matching, local functions, and ref returns
  • Work efficiently with C# data types, operators, control flow, methods, and parameters

  1. I noticed on Amazon that the 6.0 book is 24 pages shorter than 5.0 even though one would expect more content. I realize there are many reasons that could account for this but I was curious if anything was removed since the previous edition, and if so, what exactly? I was just going to sell my 5.0 book but I’m hesitant to do so if there’s anything exclusive in it.

    1. Hi Miles… The reason for the reduced page count is because we eliminated an appendix chapter on Multithreading prior to C# 5.0 and moved it to a download exclusively. I believe this material is even more dated than it was for Essential C# 5.0 such that printing it was not of sufficient value to the reader. As it turns out, we did add pages for C# 6.0 but without removing any the book would have been too long for the binding – so it is a good thing we cut the appendix anyway. :)
      Thanks!

  2. Regarding translation to Norwegian:
    2 years ago i started to translate Essentials C# 4.0 third edition, to Norwegian. I have now finished the translation, but i have not published it yet since i wanted to upgrade the book to Essentials C# 5.0 fourth edition, or Essential C# 6.0. I was reading an review by Ian Eliot regarding Essentials C# 5.0. He said that it was not much difference between Essentials C# 4.0 third edition – which i have translated, and Essentials C# 5.0 fourth edition. Now i need to know, what’s best to do, upgrade the translation from Essential C# 4.0 to Essentials C# 5.0 fourth edition, or to Essentials C# 6.0? When vil Essentials C# 6.0 be published?
