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 this example, we are creating an Employee class with three fields to represent the ID, first name, and last name of an employee."

A block of code is set as follows:

class Employee
{
    public int    EmployeeId;
    public string FirstName;
    public string LastName;
}

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 struct Vector
{
    public float x;
    public float y;
    private readonly float SquaredRo => (x * x) + (y * y);
    public readonly float GetLengthRo() => MathF.Sqrt(SquaredRo);
    public float GetLength() => MathF.Sqrt(SquaredRo);
}

Any command-line input or output is written as follows:

cd HelloSolution
dotnet new console -o Hello
dotnet sln add Hello

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "When creating a new project, select Console App (.NET Core)."
