Welcome

- It's often the case that a lot of programming problems can be solved many ways. A developer might find one solution for a problem while another may have a different fix to solve the same problem. This creates a need for consistent approaches to fix issues. Consistent patterns that avoid issues. And that's what this course is all about. Hi, I'm Reynald Adolphe and welcome to C# design patterns. Software design patterns define solutions to problems programmers often find in real-world applications.

In this course, I'll cover the origins of some well-known patterns created by a group of computer scientist called the Gang of Four. As well as the three categories their patterns fall into: Creational, Structural, and Behavioral. Then I'll jump right into describing and demonstrating a few patterns in C#. While I won't cover all 23 Gang of Four patterns, I will discuss Factory Method, Abstract Factory, Decorator, Observer, Singleton, and Iterator.

Finally, I'll cover a couple of non-Gang of Four patterns that are often used in dot net, like Repository and Unit of Work. Implementing design patterns in C# keeps code clean, concise, easy to maintain, and it adheres to the solid principles of object-oriented programming. So let's go ahead and get it started.
