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: "Here, if you put a breakpoint in the ImageFile class's constructor, it would be hit only when the Value method of the System.Lazy class is called."

A block of code is set as follows:

Lazy<ImageFile> imageFile = new 
 Lazy<ImageFile>(() => new ImageFile("test"));
var image = imageFile.Value.LoadImage;

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

Host.CreateDefaultBuilder(args)
    .ConfigureAppConfiguration((context, 
     config) =>
    {
        config.AddSql("Connection 
         string","Query"); 
    })
    .ConfigureWebHostDefaults(webBuilder =>
    {
        webBuilder.UseStartup<Startup>();
    });

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

dotnet new classlib -o MyLibrary

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "In installation options, from Workloads, select .NET Core cross-platform development for .NET Core applications, as shown in the following screenshot."
