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: “Blazor apps are built using Razor components. The first Razor component in our app is Main and it is defined in Main.razor.”

A block of code is set as follows:

private async Task<bool> UpdateItemAsync(string key, string value)
{
  if (listGroupItem == null) return false;
  if (string.IsNullOrEmpty(key) || string.IsNullOrEmpty(value)) 
    return false;
  listGroupItem.Name = key;
  listGroupItem.Notes = value;
  if (_isNewItem) {...}
  else {...}
  StateHasChanged();
  return true;
}

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

[default]
exten => s,1,Dial(Zap/1|30)
exten => s,2,Voicemail(u100)
exten => s,102,Voicemail(b100)
exten => i,1,Voicemail(s0)

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

git clone -b chapter09
https://github.com/PacktPublishing/.NET-MAUI-Cross-Platform-Application-Development

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: “We can right-click on the project node and select Add -> New Item… -> Razor Component in the project template.”
