How to send Nfe XML to SEFAZ WS using C#?

Question

I have been doing a lot of research, reading several source codes of other languages and never found answer to my question, which method of SEFAZ web services I should call?

I’m working with this WS http://nfe.fazenda.mg.gov.br/nfe2/services/NfeRetRecepcao2?wsdl

Last year on a forum, http://social.msdn.microsoft.com/forums/vstudio/pt-BR/c75142b6-ad8a-43ee-9113-b2e9e9353b1b/acessando-webservice-da-nfe-da-sefaz I raised the following question:

The WS above has the class Nferecepcao2soapclient. At instance it is obtained only the nfeRecepcaoLote2 method that accepts arguments by which it is not an XML string and returns an Object array.

So I ask, how do I send XML to SEFAZ? Does anyone at least have any notion?

Answer 1

I don’t use the webservice calls using the add Ference, don’t do that. It is a great job, and the Sefaz are not standardized, because it has been that it is different.
