Design Patterns in C#,
Are you still coding by intuition?

You will clearly understand design patterns, the core of software design, through C# and learn how to apply them to actual code.
Beyond simply acquiring theoretical knowledge, you will develop practical skills to solve complex design problems encountered in real-world work and quickly grasp other developers' code.


If you're a developer with 3 or more years of experience, you've probably wondered at least once, 'Why is this code so complex?' or 'Isn't there a better design?'

Have you ever felt anxious that adding a new feature might affect existing code, or felt overwhelmed when you had to modify legacy code?

Another developer might use pattern terminology that others may not understand. To solve this problem

The course teaches design patterns.

Through a systematic learning process, you can perfectly master design patterns and SOLID principles, and solve complex design problems by writing code in a formalized way.
Start the transformation right now.


Learning Design Patterns with C#:
From SOLID Principles to Design Patterns

Learn clear code design and grow into a developer flexible to change.

Domestic Exclusive Course: C#-based, Systematic Design Patterns Course (2025-12-22)



When this course is completed, you will


Develop the ability to design code that enhances readability and improves maintainability.

  • You will systematically learn design patterns to structure complex software designs clearly and efficiently. You'll be able to quickly and accurately understand code written by other developers, enhancing collaboration efficiency.

You will fully understand and be able to apply SOLID, the core principles of object-oriented design.

  • Understand the meaning of each SOLID principle clearly and learn how to apply them to C# code through concrete examples. Through this, you will build a foundation for designing flexible and scalable software that can adapt to changes.

Enhance your problem-solving abilities by applying various design patterns to your code.

  • Learn over 20 core design patterns including creational, structural, and behavioral patterns, and through practice applying them to actual C# projects, develop the ability to effectively solve various design problems that arise in the software development process.

Cultivate essential expertise for developers with 3+ years of experience.

  • You will develop the deep software design knowledge and practical application skills required for developers at the assistant manager level or above. You can grow into a professional who improves code quality and effectively manages complex systems.






✔️

The reason this course rapidly improves your C# design pattern skills

Learn Core Design Patterns
with C#

This course provides an in-depth exploration of all 23 GoF design patterns, including Factory Method, Singleton, Adapter, and Observer, based on the C# language. From SOLID principles to practical applications of various patterns, you can elevate your software design skills to the next level through a systematic curriculum.

Practical Design Pattern Application

Through C# example code, you'll directly solve software design problems that frequently occur in real-world practice. In particular, you can solidify theory and develop practical skills through actual code implementation and analysis of Creational, Structural, and Behavioral patterns.

Rich C# Code Resources

All design pattern examples covered in the course are provided in C# code. Beyond simply following along with the code, detailed code explanations are provided to help you clearly understand the purpose and workings of each pattern and apply them to real projects.

Build solid SW design with C#,

Section 1

Introduction to Design Patterns and SOLID Principles

This course introduces the concept of design patterns and provides an in-depth study of SOLID, the five principles of object-oriented design, through the C# language. Through this, you will learn how to improve code readability and maintainability.

Section 2

Creational Patterns

This covers design patterns that encapsulate the object creation process to write flexible and reusable code. You'll learn Factory Method, Abstract Factory, Singleton, Prototype, and Builder patterns with C# examples.

Section 3

Structural Patterns

Learn design patterns that focus on creating larger structures by combining classes and objects. Master how to apply Adapter, Bridge, Composite, Decorator, Facade, Flyweight, and Proxy patterns to actual code.

Section 4

Behavioral Patterns

Learn about design patterns that handle interactions between objects and the distribution of responsibilities. The goal is to implement and understand various behavioral patterns in C#, including Command, Chain of Responsibility, Iterator, Mediator, Observer, and Strategy.

We can help solve
these concerns!

📌

C# Developers with 3+ Years of Experience

Various design pattern terms feel unfamiliar, and you struggle to grasp how to apply them to actual code,
making it difficult to understand colleagues' code or navigate the design process

📌

New Project Design Lead

To improve the maintainability of existing code and enable efficient collaboration with team members,
for those who want to introduce systematic and reusable design principles

📌

Developers with no experience learning regular expressions

Those who are encountering various design patterns including SOLID principles for the first time,
and want to build a foundation for solving complex design problems that arise in practical work
