C# 7.0 brings a lot of new functionality to the C# language. If you were left wanting more after the release of C# 6.0, then C# 7.0 will not disappoint you at all. It focuses on consuming data, simplifying code, and improving performance. Mads Torgersen who is the C# Program Manager noted that C# 7.0's biggest feature by far is Tuples. The other is pattern matching. These two features (as well as the others) were met with enthusiasm from C# developers worldwide. It is, therefore, no guess that developers will immediately start implementing these new features introduced in C# 7.0. It will, therefore, be very beneficial to get to grips with what C# 7.0 has to offer and implement the new language features in your development projects as soon as possible.
Throughout this book, I will be using the release candidate of Visual Studio 2017. Some features and methods of doing things might change between the time of writing and the final release of Visual Studio 2017.
