C# Expert-C# Expert for .NET 8 Guidance

Example

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

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.

Example

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

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.

Example

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

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.
