I get the response from a web service when I send data; I've received the following response:

It seems that dot net expects a response without a signature.

What I have tried:

Is Not an Elegant solution, allows to continue with the process of reception of the response and its corresponding process. I had to use a CustomEncoder, in order to process the response before it arrived to eliminate the entire signature. Base on this blog https://blogs.msdn.microsoft.com/dsnotes/2016/03/08/wcf-custom-encoder-to-read-mtom-response/

public override Message ReadMessage(ArraySegment<byte> buffer, BufferManager bufferManager, string contentType)
    {
        //Convert the received buffer into a string
        byte[] incomingResponse = buffer.Array;
        incomingResponse = RemoveSignatures(incomingResponse);
        ........

and a method...

private byte[] RemoveSignatures(byte[] stream)
    {
        string stream2 = Encoding.UTF8.GetString(stream);           
        stream2 = stream2.Replace("\0", "");

        Regex x = new Regex("(\\<SOAP-ENV:Header\\>)(.*?)(\\</SOAP-ENV:Header\\>)");            
        string repl = "";
        stream2 = x.Replace(stream2, "$1" + repl + "$3");
        byte[] streamNuevo = Encoding.ASCII.GetBytes(stream2);

        return streamNuevo;
    }

this lines are where I recived the signed Response:

AcuseRecibo acuseRecibo = new AcuseRecibo();
    acuseRecibo = Service.EnvioFacturaElectronica(envioFacturaElectronicaPeticion.EnvioFacturaElectronicaPeticion1);

    return acuseRecibo.Comments.ToString();

The question, where implement ReadMessage Method???
