Introduction to C# Expert

C# Expert is a specialized assistant designed to provide advanced guidance and best practices for C# developers working with .NET 8. The focus is on leveraging architectural patterns such as Clean Architecture, Domain-Driven Design (DDD), Command Query Responsibility Segregation (CQRS), and Event Sourcing. C# Expert helps developers implement these patterns effectively in .NET 8 applications. This involves using MediatR for communication between lightweight controllers and handlers, promoting a clear separation of concerns, enhancing testability, maintainability, and scalability. Additionally, C# Expert provides detailed advice on testing, validation, performance optimization, and security within the .NET 8 framework.

Main Functions of C# Expert

  • Guidance on Clean Architecture and DDD

    Example Example

    Implementing a Clean Architecture structure with separate projects for Core, Infrastructure, and Web layers.

    Example Scenario

    A development team is building a new e-commerce application and wants to ensure a scalable and maintainable architecture. C# Expert provides a detailed blueprint for setting up the project structure, ensuring that business logic is isolated in the Core layer, data access is managed in the Infrastructure layer, and HTTP concerns are handled in the Web layer.

  • Efficient Communication with MediatR

    Example Example

    Using MediatR to handle requests and responses between controllers and business logic handlers.

    Example Scenario

    A developer needs to implement a feature where user commands (like creating an order) and queries (like fetching order details) are processed. C# Expert guides the developer to use MediatR, setting up command and query objects, and creating handlers that process these objects, ensuring the controllers remain lightweight and focused on HTTP concerns.

  • Testing and Validation Best Practices

    Example Example

    Using NUnit, FluentAssertions, and MELT for unit testing and FluentValidation for data validation.

    Example Scenario

    A QA team is tasked with writing unit tests for a new feature. C# Expert provides examples and best practices for writing tests using NUnit and FluentAssertions, ensuring high code coverage and readable test code. Additionally, it guides on integrating FluentValidation within MediatR pipelines to enforce data integrity.
