Complete Design Pattern's Guide

Course Overview

This course provides a comprehensive overview of Design Patterns in C# and .NET from a practical perspective. This course in particular covers patterns with the use of:

The latest versions of C# and the .NET framework

Use of modern programming approaches: dependency injection

Discussions of pattern variations and alternative approaches

This course provides an overview of all the Gang of Four (GoF) design patterns , together with modern-day variations, adjustments, discussions of intrinsic use of patterns in the language.

The best way to learn design pattern is by doing . If you learn something with a doing you learn quickly and you learn to the point.

What are Design Patterns?

Design Patterns are reusable solutions to common programming problems. They were popularized with the 1994 book Design Patterns: Elements of Reusable Object-Oriented Software by Erich Gamma, John Vlissides, Ralph Johnson and Richard Helm (who are commonly known as a Gang of Four, hence the GoF acronym).

The appeal of design patterns is immortal: we see them in libraries, some of them are intrinsic in programming languages, and you probably use them on a daily basis even if you don't realize they are there.

What Patterns Does This Course Cover?

This course covers all the GoF design patterns. In fact, here's the full list of what is covered:

Creational Design Patterns: Builder, Factories (Factory Method and Abstract Factory), Prototype and Singleton

Structrural Design Patterns: Adapter, Bridge, Composite, Decorator, Façade, Flyweight and Proxy

Behavioral Design Patterns: Chain of Responsibility, Command, Interpreter, Iterator, Mediator, Memento, Null Object, Observer, State, Strategy, Template Method and Visitor

Who Is the Course For?

This course is for .NET/C# developers who want to see not just textbook examples of design patterns, but also the different variations and tricks that can be applied to implement design patterns in a modern way.

Presentation Style

This course is presented as a (very large) series of live demonstrations being done in Microsoft Visual Studio. Most demos are single-file, so you can download the file attached to the lesson and run it in Visual Studio, Visual Studio Code, Rider or another IDE of your choice.

This course does not use UML class diagrams; all of demos are live coding. I use Visual Studio

One of the shortcomings of learning with a project is you can not implement all design patterns in one project. So to cover them i have also created individual videos for each design pattern. These specific videos goes more in-depth in to those individual design pattern videos.

Happy learning.
