In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Once all of this is in place, you can just tell your ORM to save an instance of the Customer class."

A block of code is set as follows:

SELECT a_.FirstName,
  a_.LastName,
  a_.EmailAddress,
  a_.Age
FROM tblCustomer a_
WHERE a_.Age > 28 AND a_.Age < 35

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 interface IRepository<T> where T : EntityBase<T>
{
  void Save(T entity);
  void Update(int id, Employee employee);
  T GetById(int id);
  IEnumerable<T> Apply(ISpecification<T> specification);
}

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Next, we click on the Install button that appears next to NUnit."
