The C# Workshop

By: Jason Hales, Almantas Karpavicius, Mateus Viegas

Overview of this book

C# is a powerful, versatile language that can unlock a variety of career paths. But, as with any programming language, learning C# can be a challenging process. With a wide range of different resources available, it’s difficult to know where to start. That's where The C# Workshop comes in. Written and reviewed by industry experts, it provides a fast-paced, supportive learning experience that will quickly get you writing C# code and building applications. Unlike other software development books that focus on dry, technical explanations of the underlying theory, this Workshop cuts through the noise and uses engaging examples to help you understand how each concept is applied in the real world. As you work through the book, you'll tackle realistic exercises that simulate the type of problems that software developers work on every day. These mini-projects include building a random-number guessing game, using the publisher-subscriber model to design a web file downloader, creating a to-do list using Razor Pages, generating images from the Fibonacci sequence using async/await tasks, and developing a temperature unit conversion app which you will then deploy to a production server. By the end of this book, you'll have the knowledge, skills, and confidence to advance your career and tackle your own ambitious projects with C#.

Working with a Database in Enterprise

When talking about databases, you usually imagine SQL or another language to talk with them. On top of that, another language (C#, in this case) is most often used to connect to a database to execute SQL queries. If not controlled, C# gets mixed with SQL, and it causes a mess of your code. Over the years, there have been a few patterns refined to implement the communication with a database in a clean way. Two such patterns, namely, Repository and CQRS, are commonly used to this day.

Repository Pattern

The Repository is a pattern that targets a model and defines all (if needed) possible CRUD operations. For example, if you take a Product model, you could have a repository with this interface:

public interface IProductRepository
{
    int Create(Product product);
    void Delete(int id);
    void Update(Product product);
    Product Get(int id);
