E o outro endpoint irá listar, em ordem de criação, todos os cartões de um solicitante (utilizando e-mail como parâmetro). </p> <p>Implementação deverá ser escrita utilizando C#, .Net Core e Entity Framework Core. </p> <p>Para iniciar o processo vamos precisar: </p> <p>Visual Studio Code (versão compativel com seu sistema): <a
