I'm trying this way (asynchronous), with the sync I also can not capture any status or return, but at least transmits the note to MG's
With NfeRecepcaoMG
.Url = "https://nfe.fazenda.mg.gov.br/nfe2/services/NfeAutorizacao?wsdl"
.nfeCabecMsgValue = xCabecalho2
.Timeout = 50000
.ClientCertificates.Add(cert)
.SoapVersion = Web.Services.Protocols.SoapProtocolVersion.Soap12
.NfeAutorizacaoLoteAsync(NfeRecepcaoMGmsg)
End With
