Designing ASP.NET Core Applications with SOLID and Clean Architecture

Writing code that works is only the first step; writing code that adapts to change without breaking is the real challenge. As web applications grow, poor design choices lead to tangled codebases that are difficult to maintain, test, and scale. This text-based course guides you through structured software design using ASP.NET Core. You will transition from writing monolithic scripts to crafting decoupled, robust architectures. By understanding foundational software principles and layering patterns, you will build applications that remain flexible, testable, and clean over time. What you'll learn: 1. Understand the fundamental terminology of software architecture and the core definitions of SOLID design principles. 2. Apply Clean Architecture patterns to separate business logic from external frameworks and database dependencies. 3. Configure dependency injection in ASP.NET Core to achieve loose coupling and enhance testability. 4. Implement modern C# features and clean coding practices to improve code readability and maintainability. 5. Design robust data-access layers using the repository pattern and modern Entity Framework Core practices. 6. Structure automated unit tests using modern testing frameworks to validate your decoupled architectural layers. The course begins with foundational software design concepts and architectural terminology before guiding you step-by-step through the implementation of a Clean Architecture template. You will read comprehensive explanations, study clean code structures, and analyze practical architectural patterns. Designed for beginner-to-intermediate developers who are familiar with basic C# syntax and want to transition into professional software design, this course requires no prior architectural experience.
