Solid Principles for Clean Code Programming & Architecture | Udemy Coupons 2025

Master SOLID Principles for Clean Code and Software Architecture

In this course, you will master the SOLID principles of software design and software architecture to write clean code in C#. Designed for both beginners and experienced developers, this course covers the SOLID programming principles essential for building scalable, maintainable, and robust software.

What You’ll Learn:

• SOLID Design Principles: Learn how the SOLID principles, originally introduced by Robert Martin in Agile Software Development: Principles, Patterns, and Practices, shape the foundation of modern software architecture.
• Real-World Application: See how to apply SOLID principles in C#, Java, and other object-oriented programming languages through practical examples and real-world case studies.
• Importance of SOLID: Understand why SOLID programming principles are critical for creating flexible, scalable, and clean code.
• Applying SOLID Principles: Learn step-by-step how to implement SOLID principles in real-life projects to ensure your software architecture is clean, modular, and future-proof.

Topics Covered:

Single Responsibility Principle (SRP)

• What is SRP in OOP languages like C# and Java
• Why SRP is a fundamental SOLID principle in software design
• How to implement SRP to create more focused and maintainable classes

Open-Closed Principle (OCP)

• Understanding OCP in languages like C# and Java
• How OCP supports extensible and adaptable software architecture
• Practical examples of applying OCP in real-world scenarios

Liskov Substitution Principle (LSP)

• What is LSP in OOP languages like C# and Java
• Why LSP is crucial for flexible and reliable code
• How to ensure LSP compliance in your codebase

Interface Segregation Principle (ISP)

• The role of ISP in designing lean and efficient interfaces
• Why ISP is important for modular software architecture
• Real-world examples of implementing ISP

Dependency Inversion Principle (DIP)

• What is DIP and how it enhances your software architecture
• Why DIP is a key component of SOLID programming principles
• How to use DIP in your projects for better modularity and decoupling

Dependency Injection (DI) and Inversion of Control (IOC)

• Implementing Dependency Injection (DI) with IoC containers like Unity
• Understanding the difference between DI, DIP, and IOC
• How to use DI to improve your software’s flexibility

Beyond SOLID:

In addition to the SOLID design principles, we’ll also cover other important programming concepts such as:

• DRY (Don’t Repeat Yourself)
• KISS (Keep It Simple, Stupid)
• GRASP (General Responsibility Assignment Software Patterns)
• YAGNI (You Aren’t Gonna Need It)
• Opportunity Cost Principle
• Big Design Up Front & Rough Design Up Front
• Single Source of Truth
• Principle of Least Astonishment

Hands-On Case Study:

You will put the SOLID principles into practice by building an Employee Management Portal. This real-world case study will guide you through implementing each SOLID principle as part of a complete software architecture. Even if you’re not familiar with C#, these SOLID programming principles apply across multiple languages like Java, JavaScript, Python, and more.

By the end of this course, you’ll have a solid understanding of the SOLID principles, enabling you to write clean code and create robust software architecture. Plus, we’ll prepare you for common interview questions on SOLID principles, giving you the skills needed to succeed in software development roles.
