Description

Master SOLID Principles for Clean Code and Software ArchitectureIn 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 JavaWhy SRP is a fundamental SOLID principle in software designHow to implement SRP to create more focused and maintainable classesOpen-Closed Principle (OCP)Understanding OCP in languages like C# and JavaHow OCP supports extensible and adaptable software architecturePractical examples of applying OCP in real-world scenariosLiskov Substitution Principle (LSP)What is LSP in OOP languages like C# and JavaWhy LSP is crucial for flexible and reliable codeHow to ensure LSP compliance in your codebaseInterface Segregation Principle (ISP)The role of ISP in designing lean and efficient interfacesWhy ISP is important for modular software architectureReal-world examples of implementing ISPDependency Inversion Principle (DIP)What is DIP and how it enhances your software architectureWhy DIP is a key component of SOLID programming principlesHow to use DIP in your projects for better modularity and decouplingDependency Injection (DI) and Inversion of Control (IOC)Implementing Dependency Injection (DI) with IoC containers like UnityUnderstanding the difference between DI, DIP, and IOCHow to use DI to improve your software’s flexibilityBeyond 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 PrincipleBig Design Up Front & Rough Design Up FrontSingle Source of TruthPrinciple of Least AstonishmentHands-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.
