Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “In the custom.css file, you can write the columns property and see how VS suggests a code snippet for it.”

A block of code is set as follows:

if (OperatingSystem.IsLinux()){
    return new List<WeatherForecast>();

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public float Calculate(int value){
   return (float)((value + 126) * (Math.PI / value));
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Go to the Tools | Options menu.”
