I am trying to create a SOAP web service to use with a client.

According to the documentation, we have to create a web service with two methods that return certain information. I have created them without a problem, but I can not get them to fit the example format.

I have to say that for years I did not create any SOAP services (since Net 2.0) because I have been doing REST services for a long, so if you see any nonsense, forgive me.

The example request that there is in the documentation (the good one) is this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:pag="http://pagorecibos.pagosrecibos.com/"> 
    <soapenv:Header/>
    <soapenv:Body>
        <pag:obtenerImporte>
            <referencia>040</referencia>
        </pag:obtenerImporte>
    </soapenv:Body>
</soapenv:Envelope>
That's the format that my service want to recieve:
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <obtenerImporte xmlns="http://tempuri.org/">
      <referencia>string</referencia>
    </obtenerImporte>
  </soap:Body>
</soap:Envelope>
The code of my service is this:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service: System.Web.Services.WebService
    [WebMethod]
    [SoapDocumentMethod(ParameterStyle = SoapParameterStyle.Bare)]
    public string ObtenerImporte(ObtenerImporte obtenerImporte)
        return "Hola a todos";
    [WebMethod]
    [SoapDocumentMethod(ParameterStyle = SoapParameterStyle.Bare)]
    public string RealizarPago(RealizarPago realizarPago)
        return "Hola a todos";
Class (the other class is similar):
public class ObtenerImporte
    [XmlElement("referencia")]
    public string Referencia { get; set; }
The difference is in the namespace and the prefix in node "obtenerImporte" but I can't resolve it.
I'm using VS2017 Community Edition y created the project using "ASP.NET Web Service" template.
                Just change http://tempuri.org/ to http://pagorecibos.pagosrecibos.com/ and that would make it essentially equivalent xml (that is, without imported namespace, but then who cares, your service should accept that top payload)

                Thanx for your answers. The problem is that the format is not equal and, when I try to make a request with the "original" format throws an error (sorry is in Spanish):  System.Web.Services.Protocols.SoapException: No se puede controlar la solicitud sin un parámetro de acción válido. Proporcione una acción SOAP válida.    en System.Web.Services.Protocols.Soap12ServerProtocolHelper.RouteRequest()    en System.Web.Services.Protocols.SoapServerProtocol.RouteRequest(SoapServerMessage message)

Problem solved!!!. Adding and removing code.... suddenly it works :D. The right way to define the service is this (thanks @zaitsman for your clue):
[WebService(Namespace = "http://pagorecibos.pagosrecibos.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
    [WebMethod]
    [SoapDocumentMethod(Use = SoapBindingUse.Literal, ParameterStyle = SoapParameterStyle.Bare)]
    public string ObtenerImporte(ObtenerImporte obtenerImporte)
        return "Obtener Importe";
    [WebMethod]
    [SoapDocumentMethod(ParameterStyle = SoapParameterStyle.Bare)]
    public string RealizarPago(RealizarPago realizarPago)
        return "Realizar Pago";
I hope that this solution could help other one.
