Decoupling Data Access: Repository Pattern in ASP.NET Core

When database logic is tangled with business rules, software becomes fragile and difficult to test. Standardizing your data access layer is the key to building scalable, enterprise-grade web applications. This text-based course guides you through abstracting your data layer using the Repository Pattern in ASP.NET Core. You will learn how to decouple your application from specific database technologies, making your codebase cleaner, easier to maintain, and ready for automated testing. What you'll learn: - Understand the core concepts of the Repository and Unit of Work architectural patterns. - Implement generic and specific repositories using Entity Framework Core. - Configure dependency injection in ASP.NET Core to manage repository lifetimes. - Apply modern C# features to write clean, concise data transfer objects and repository interfaces. - Write unit tests for your business logic by mocking repository interfaces. - Refactor tightly-coupled data access code into clean, separated layers. You will start with the fundamental definitions of data abstraction and architectural separation before moving step-by-step through practical code implementations. Through clear written explanations and realistic code snippets, you will master the transition from direct database queries to a clean repository architecture. This course is designed for beginner to intermediate developers who want to improve their software architecture skills. Familiarity with basic C# is helpful, but no prior experience with design patterns is required. Start reading today to write cleaner, more maintainable ASP.NET Core applications.
