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: “Request delegates are configured using the Run, Map, and Use extension methods, typically configured in the Program.cs file.”

A block of code is set as follows:

string key1 = _configuration.GetValue<string>
  ("MyCustomSetting:Key1");
string key2 = _configuration.GetValue<string>
  ("MyCustomSetting:Key2");

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

var builder = WebApplication.CreateBuilder(args);
 // Add configuration from environment variables
builder.Configuration.AddEnvironmentVariables();
// Add configuration from command-line arguments
builder.Configuration.AddCommandLine(args);
var app = builder.Build();
app.Run();

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

dotnet add package Microsoft.Azure.AppConfiguration.AspNetCore

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: “On the next screen, click on the +Create option to add the new resource.”
