Course Description

In 1994 the "Gang of Four" published a book titled "Design Patterns: Elements of Reusable Object-Oriented Software". This book contains 23 fundamental software design patterns. It is regarded as the standard reference manual for object-oriented design theory and practice.

In this course I will teach you the first 12 design patterns. These are all 5 creational- and all 7 structural design patterns. You use these patterns to create new objects efficiently and to create structure in your application architecture.

By the end of the course you will be fluent in all 12 design patterns. With this knowledge you will be well on your way to become a Senior Application Architect.

Why should you take this course?

You should take this course if you are a beginner or intermediate C# developer and want to take your career to the next level. Some of the patterns (e.g. 'Bridge') might sound very complicated, but all of my lectures are very easy to follow, and I explain all topics with clear code and many instructive diagrams. You'll have no trouble following along.

Or maybe you're working on the application architecture of a large project, and you need to create a robust design that is instantly clear to your team members? The patterns in this course will help you immensely.

Or maybe you're preparing for a C# related job interview? This course will give you an excellent foundation to answer any software architecture questions they might throw at you.

The course is very well structured with the description of the intent, the participants in the pattern, the UML design pattern as well as a Real World example project on how to apply the pattern to a project. Very concise and straight to the point. Very well crafted course!

I wasn't sure what to expect at first, but I'm impressed, and I am also happy. I could write a couple of pages on my pedagogical philosophy and why this course makes me happy, but... to keep a story short: This is the first time I have heard of the Gang of Four and the book "Design Patterns: Elements of Reusable Object-Oriented Software". I am very happy to see that this book appears to be, what I would personally describe, as the Computer Science equivalent of Daniel J. Velleman's "How To Prove It: A Structured Approach" for aspiring mathematicians (I myself having an MS in math). Having examples to follow is great and, for me, very important. I surmise this is as good as things are going to get for a Udemy course, as I get a chunk of good educational value if I have an exercise set to chomp through. This is basically a primer to getting the Gang of Four's book and reading through it.

Really good course, I enjoyed very much the structure of each lesson and the way the concepts are reviewed along the course. For me personal preferences, I would prefer if the examples we're built along the video, instead explaining a pre-made example. Anyway, each project is explained and we have access to the source code. I recommend, it's a great course.

Recommend to learn the second part as well.

By David RIEHL on 9/15/2020

A good approch and good examples for design patterns

By Jaikishen Goel on 8/26/2020

Good.

By Ali Majed on 6/20/2020

I'd prefer that the example were implemented from scratch so the student can interact with it, knowing what is the problem and then implement the corresponding design pattern, better than go through a finished solution, but anyway good course.

By Md.Shoikat Chowdhury on 6/19/2020

It should be example based learning. First come with scenario and then come to implement

By Jakub Daszkiewicz on 4/6/2020

This is the best course on design patterns I've ever seen.

By Daniel Terceros on 1/25/2020

Awesome course. If someone doesn't like Mark's explaining slow just increase video speed as 1.25

By Kishore Kumar Thekke Veedu on 1/17/2020

The course is neatly composed .

By Charles on 10/7/2019

I need to do more examples to apply to my code.
