Entity Framework 6: Error getting SQL Server record

Question

I can enter records in the bank normally, however, when trying to get, it gives error in EF.

public class Program {
    public static void Main(string[] args) {
        new ClienteConsole().ConsoleListarCliente(1);
    }
}

public class ClienteConsole {
    public void ConsoleListarCliente(int matricula)
    {
        try
        {
            var dao = new ClienteDao();
            var cliente = dao.ObterCliente(matricula);
            ...
        }
        catch (Exception e)
        {
            System.Console.WriteLine(e.Message);
            System.Console.WriteLine(e.StackTrace);
        }
    }
}

public class ClienteDao
{
    private MyContext _db = new MyContext();

    public void Cadastrar(Cliente cliente)
    {
        _db.Set<Cliente>().Add(cliente); //Sem erro.
        _db.SaveChanges();
    }

    public Cliente ObterCliente(int matricula)
    {
        return _db.Set<Cliente>().Find(matricula); //Erro.
    }
    ...
}

An exception was triggered by the destination of a call.

After removing the "Try-catch" structure, the following exception is released:

Invalidoperationexception: The class 'Client' has no parameterless constructor.

Answer 1

Entity Framework requires a constructor with no parameters in models.

public class Cliente
{
    public Cliente() { }
}
