Create the solution

dotnet new sln -n BookStore

Create projects within the solution

dotnet new webapi -n BookStore.API -controllers -o src/BookStore.API dotnet new classlib -n BookStore.Domain -o src/BookStore.Domain dotnet new classlib -n BookStore.Infrastructure -o src/BookStore.Infrastructure dotnet new xunit -n BookStore.Tests -o tests/BookStore.Tests

Add projects to the solution

dotnet sln add (ls -r **/*.csproj) # in powershell

dotnet sln add src/BookStore.API/BookStore.API.csproj dotnet sln add src/BookStore.Domain/BookStore.Domain.csproj dotnet sln add src/BookStore.Infrastructure/BookStore.Infrastructure.csproj dotnet sln add tests/BookStore.Tests/BookStore.Tests.csproj

Steps:

1. Domain Layer (BookStore.Domain): Define your domain entities and business logic. Start by implementing the Book class, representing the core entity in your application.

Create Book.cs in the Domain project

touch src/BookStore.Domain/Book.cs

2. Infrastructure Layer (BookStore.Infrastructure): Implement the data access layer and database-related functionalities. Create the DbContext class, which represents your database context and defines the database schema. Implement repositories to interact with the database. Start by defining the interfaces (IBookRepository) and their implementations (BookRepository).

Add Entity Framework Core package to Infrastructure project

dotnet add src/BookStore.Infrastructure/BookStore.Infrastructure.csproj package Microsoft.EntityFrameworkCore.SqlServer

Create ApplicationDbContext.cs in the Infrastructure project

touch src/BookStore.Infrastructure/ApplicationDbContext.cs

Create IBookRepository.cs and BookRepository.cs in the Infrastructure project

mkdir src/BookStore.Infrastructure/Repositories touch src/BookStore.Infrastructure/Repositories/IBookRepository.cs touch src/BookStore.Infrastructure/Repositories/BookRepository.cs

3. Application Layer (BookStore.Application): Implement the application services that orchestrate business logic and interact with the infrastructure layer. Create the IBookService interface, which defines the contract for operations related to books. Implement the BookService class, which provides the actual implementation of book-related operations using the repositories from the infrastructure layer.

Create IBookService.cs and BookService.cs in the Application project

mkdir src/BookStore.Application/Books touch src/BookStore.Application/Books/IBookService.cs touch src/BookStore.Application/Books/BookService.cs

4. Presentation Layer (BookStore.API): Implement the API controllers and models. Create the BooksController class, which defines the API endpoints for managing books (e.g., CRUD operations). Define the BookDTO class, which represents the data transfer object used for transferring book-related data between the client and server.

Add FluentValidation package to API project

dotnet add src/BookStore.API/BookStore.API.csproj package FluentValidation.AspNetCore

Create BookDTO.cs in the API project

touch src/BookStore.API/Models/BookDTO.cs

Create BooksController.cs in the API project

mkdir src/BookStore.API/Controllers touch src/BookStore.API/Controllers/BooksController.cs
