It promotes the separation of concerns through multiple layers and enforces boundaries between them. In this response, I'll provide an overview of Clean Architecture principles and show you a sample code structure in .NET 7. Clean Architecture Principles: Separation of Concerns: The codebase is divided into distinct layers, each with its own responsibilities and concerns. Dependency Rule: Dependencies flow inward, meaning outer layers do not depend on inner layers. This allows for easy replacement or modification of components. Abstraction over Implementation: Interfaces and abstractions are used to define contracts, decoupling high-level modules from low-level details. Testability: The architecture facilitates unit testing by enabling isolated testing of components at different levels. Independence of Frameworks: The core business logic is not dependent on any specific framework or library, making it more portable and maintainable. Sample Code Structure: Here's an example of a sample code structure in .NET 7 based on Clean Architecture principles: Presentation Layer (Web/API) This layer interacts with the user and handles HTTP requests and responses. It depends on the Application layer. It contains controllers, view models, and other UI-related components. Application Layer This layer contains application-specific business logic and coordinates interactions between the Presentation and Domain layers. It depends on the Domain layer. It contains use cases, application services, and mappers. Domain Layer This layer represents the core business logic of the application. It is independent of other layers and contains domain models, entities, interfaces, and domain services. Infrastructure Layer This layer provides implementations for external dependencies, such as databases, external services, or third-party libraries. It depends on the Domain and Application layers. It contains data access implementations, repositories, external service clients, and other infrastructure-specific components. Entity Framework Core (EF Core) is an object-relational mapping (ORM) framework developed by Microsoft. It is a part of the larger .NET ecosystem and is specifically designed for data access in .NET applications. EF Core enables developers to interact with relational databases using object-oriented programming concepts. It simplifies the process of querying, inserting, updating, and deleting data from the database by providing a set of APIs and conventions. Key features of Entity Framework Core include: Object-Relational Mapping: EF Core maps database tables to .NET objects, allowing developers to work with data using object-oriented paradigms. It eliminates the need for writing low-level SQL queries manually. LINQ Support: EF Core supports Language-Integrated Query (LINQ), which allows developers to write queries against the database using familiar C# syntax. This makes querying and manipulating data more intuitive and less error-prone. Database Providers: EF Core supports multiple database providers, including SQL Server, MySQL, PostgreSQL, SQLite, and more. This enables developers to work with different database systems using a consistent API. Migration: EF Core includes a migration system that allows for database schema changes to be managed and applied automatically. Migrations help keep the database schema in sync with the application's data model. Cross-Platform: EF Core is designed to be cross-platform and can be used in various environments, including Windows, macOS, and Linux. This provides flexibility when developing applications targeting different operating systems. Testability and Mockability: EF Core has features that support unit testing and mocking, making it easier to test code that interacts with the database. It allows for the creation of in-memory databases or the ability to mock the EF Core context for testing purposes. Overall, Entity Framework Core simplifies database interactions in .NET applications by providing an abstraction layer between the application code and the database. It enhances productivity, reduces development time, and promotes cleaner and more maintainable code.
