- 43. Resumo Use ADO.NETem aplicações legadas – Investimento continua Use Linq To SQL em cenário que não necessita de mapeamento intenso com o banco de dados Prefira EF em maioria dos cenários (médios e complexos)
- 44. Resumo Use ADO.NETData Services Fornecer dados via Web sem restrição de acesso Fornecer dados via interfaces REST Tenha atenção ao modelo de segurança (Web) e geração de proxy
