I currently have I have an idea
Required availability As needed
Roles needed Developer, Other
Other roles needed Preciso que faça em C# (DotNet) conforme exemplo modelo abaixo que fiz do Serviço https://hnfe.fazenda.mg.gov.br/nfe2/services/NFeStatusServico4 os seguintes:
NFeConsulta4 4.00 https://hnfe.fazenda.mg.gov.br/nfe2/services/NFeConsulta4
NFeInutilizacao4 4.00 https://hnfe.fazenda.mg.gov.br/nfe2/services/NFeInutilizacao4
NFeRetAutorizacao4 4.00 https://hnfe.fazenda.mg.gov.br/nfe2/services/NFeRetAutorizacao4
OBS: Terá que me enviar os fontes exemplos para que eu faça teste e faça aprovação em minha ferramenta. Lembrando que estes WebService são MG-Minas Gerais
