Boa tarde, eu consegui resolver, eu repassei os vídeo não vi o professor falar algo sobre a WebApi ESTAR EM " FUNCIONAMENTO, quando a WebApp for executada, e o problema acima na verdade é esse que esta descrito abaixo. Então eu descobri através dessa linha que aparece no ERRO" Nenhuma conexão pôde ser feita porque a máquina de destino as recusou ativamente ", para eu poder consumir a api, ela deve estar em funcionamento, então quando coloquei a WebApi pra funcionar, e executei WebApp o programa funcionou corretamente.
