Chapter 2. Basic Programming Techniques
To use a programming language, you must master the fundamentals. You need to understand the elements required to construct a working program, and learn how to use the development tools to build and run code. You also need to become familiar with the everyday features for representing information, performing calculations, and making decisions.

And then we’ll build some slightly more interesting examples to explore the C# language.
