Estrutura de unidade de trabalho e repositório | URF oficial , entidades rastreáveis e equipe de fábrica de design
Essa estrutura (mais de 100 mil downloads no total) minimiza a área de superfície da sua tecnologia ORM de disseminação em seu aplicativo. Esta estrutura foi deliberadamente projetada para ser leve, pequena em tamanho e não intimidante para estender e manter. Quando dizemos leve, na verdade queremos dizer leve, ao usar este framework com o provedor Entity Framework existem apenas 10 classes. Essa estrutura leve permitirá que você padronize de maneira elegante, discreta e fácil seus aplicativos e sistemas com repositório, unidade de trabalho e design orientado a domínio. Usar repositórios genéricos ou não? A estrutura permite a liberdade de ambos, repositórios genéricos e a capacidade de adicionar métodos de repositório específicos ao seu próprio domínio, em suma, Unidade de Trabalho com Repositórios extensíveis e genéricos .

Todos os métodos expostos de Repository em Service são substituíveis para adicionar qualquer lógica pré ou pós-domínio/negócios. A lógica de negócios do domínio deve estar na camada de Serviço e não em Controladores ou Repositórios para separação de interesses.
ICustomerService , que sempre deve herdar IService , por exemplo, IServiceCustomerService que implementa ICustomerServicecontainer.RegisterType() , veja o próximo exemplo para obter mais detalhes sobre como conectar DI e IoC. public interface ICustomerService : IService < Customer >
{
decimal CustomerOrderTotalByYear ( string customerId , int year ) ;
IEnumerable < Customer > CustomersByCompany ( string companyName ) ;
IEnumerable < CustomerOrder > GetCustomerOrder ( string country ) ;
}
public class CustomerService : Service < Customer > , ICustomerService
{
private readonly IRepositoryAsync < Customer > _repository ;
public CustomerService ( IRepositoryAsync < Customer > repository ) : base ( repository )
{
_repository = repository ;
}
public decimal CustomerOrderTotalByYear ( string customerId , int year )
{
// add any domain logic here
return _repository . GetCustomerOrderTotalByYear ( customerId , year ) ;
}
public IEnumerable < Customer > CustomersByCompany ( string companyName )
{
// add any domain logic here
return _repository . CustomersByCompany ( companyName ) ;
}
public IEnumerable < CustomerOrder > GetCustomerOrder ( string country )
{
// add any domain logic here
return _repository . GetCustomerOrder ( country ) ;
}
