C# is a general-purpose, type-safe, object-oriented programming language. The goal of the language is programmer productivity. To this end, the language balances simplicity, expressiveness, and performance. The C# language is platform-neutral, but it was written to work well with the Microsoft .NET Framework. C# 7.0 targets .NET Framework 4.6/4.7.
The programs and code snippets in this book mirror those in Chapters 2 through 4 of C# 7.0 in a Nutshell and are all available as interactive samples in LINQPad. Working through these samples in conjunction with the book accelerates learning in that you can edit the samples and instantly see the results without needing to set up projects and solutions in Visual Studio.
To download the samples, click the Samples tab in LINQPad and click “Download more samples.” LINQPad is free—go to http://www.linqpad.net.
