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

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. "Start Visual Studio 2019, open the Tic-Tac-Toe ASP.NET Core 3 project you have created, create three new folders called Controllers, Services, and Views, and  then create a subfolder called Shared in the Views folder."

A block of code is set as follows:

    [HttpGet] 
    public IActionResult EmailConfirmation (string email) 
    { 
      ViewBag.Email = email; 
      return View(); 
    } 

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 class Student
{
    public long Id { get; set; }
    public string Name { get; set; }
    public StudentDetails StudentDetails { get; set; }
    public ICollection<StudentSubject> StudentSubjects { get; set; }
        // Added after constructed table
}

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

sudo apt-get install code

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: "Open Visual Studio 2019, go to the Team Explorer tab, and click on the Branches button."
