We\'re being really stuck here so I decided to ask your help.
Yesterday I\'ve been asked to help to consume a web service, got the URL to the WSDL, and the user cred
var factory = new ChannelFactory('*');
factory.Credentials.UserName.UserName = 'bob';
factory.Credentials.UserName.Password = 'bob';
var proxy = factory.CreateChannel();
