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: “Then, the user is authenticated if the user object inside the UserState class is not null.”

A block of code is set as follows:

<nav class="navbar navbar-expand-lg navbar-light bg-light">     ... 
      <div class="d-flex"> 
        <button class="btn btn-outline-primary"> 
           Login</button>
      </div>
    </div> 
</nav> 

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

dotnet builddotnet run

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Another example we will go through is the Add to Cart button.”
