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: "Add the DeleteProduct method to the @code block."

A block of code is set as follows:

private void DeleteProduct(Product product)
{
    cart.Remove(product);
    total -= product.Price;
}

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 CartService : ICartService
{
    public IList<Product> Cart { get; private set; }
    public int Total { get; set; }
    public event Action OnChange;
}

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

Add-Migration Init
Update-Database

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: "From the Build menu, select the Build Solution option."
