Pessoal, Estou tentando consumir um SOAP a partir do C# mas tá dando um erro chamado "SOAP negociantion". Alguem saberia o porque? Obs. estou consumindo WS so SugarCRM abraço

[RESOLVIDO] - WCF client with SOAP service

Resolvido pessoal. O App Config ficou assim:

<bindings> 
  <basicHttpBinding>
    <binding name="SecureTransport">
      <security mode="Transport">
        <transport clientCredentialType="None"/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="https://crm.acao.com/service/v4/soap.php" binding="basicHttpBinding" bindingConfiguration="SecureTransport" contract="sugar.sugarsoapPortType" name="SecureTransport"/>
</client>
  </system.serviceModel>

Além disso, é preciso setar as credenciais em ClientCredentials (aqui eu tambem tiro a validade por certificado)

ClientCredentials.UserName.UserName = "XINT_SUGAR";
            ClientCredentials.UserName.Password = "blah";
            ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
            ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, errors) => true;

Por último, dependendo da quantidade de informação trafegando, ele vai chiar, faça isso:

BasicHttpBinding binding = base.ChannelFactory.Endpoint.Binding as BasicHttpBinding;
            binding.MaxReceivedMessageSize = 20000000;
            binding.MaxBufferSize = 20000000;
            base.ChannelFactory.Endpoint.Binding = binding;
            foreach (OperationDescription op in base.ChannelFactory.Endpoint.Contract.Operations)
            {
                DataContractSerializerOperationBehavior dataContractBehavior = op.Behaviors.Find<DataContractSerializerOperationBehavior>()
                        as DataContractSerializerOperationBehavior;
                if (dataContractBehavior != null)
                {
                    dataContractBehavior.MaxItemsInObjectGraph = 20000000;
                }
            }

Espero ter ajudado, obrigado!
