HttpClient send XML PostAsync Malformed request: Premature end of file?

I am trying to send a xml to a server and it always throw an exception Malformed request: Premature end of file.. . Using the Postman it works well but using HttpClient it doesn't, I think the problem is with headers what server needs is Content-Type", "application/xml and I cannot do it works
How could I fix it ?
trying
//HttpClient
HttpClient hClient = new HttpClient();
hClient.DefaultRequestHeaders.TryAddWithoutValidation("Content-Type", "application/xml");
//post
var contentString = new StringContent(xml, Encoding.UTF8, "application/xml");
HttpResponseMessage response = hClient.PostAsync(URL_FINAL, contentString).GetAwaiter().GetResult();
var resultContent = response.Content.ReadAsStringAsync().GetAwaiter().GetResult();

SoapHeader.MustUnderstand Property
When an XML Web service client adds a SOAP header to an XML Web
service method call with the MustUnderstand property set to true, the
XML Web service method must set the DidUnderstand property to true;
otherwise, a SoapHeaderException is thrown back to the XML Web service
client by ASP.NET.

cs0103 the name'debuggerDisplayProxy' does not exist in the current context

I'm trying to construct a soap envelope to send data and, when I instantiate XmlDocument object, I'm getting this error "cs0103 the name'debuggerDisplayProxy' does not exist in the current context". I don't know what it is or how to solve it. I searched on the web and didn't find anything useful. Could you help, please?
Below, is the code where I try to do the envelope:
private static System.Xml.XmlDocument CreateSoapEnvelope(string xml)
{
var soapEnvelope = new System.Xml.XmlDocument();
soapEnvelope.LoadXml(#"<?xml version=""1.0"" encoding=""utf-8""?>
<soap:Envelope
xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/""
xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance""
xmlns:xsd=""http://www.w3.org/2001/XMLSchema"">
<soap:Body>
<HelloWorld3 xmlns=""
http://localhost:52700/api/SOAPService/PostObject"">"
+ xml +
"</HelloWorld3></soap:Body></soap:Envelope>");
return soapEnvelope;
}
Below, the error:

Consume SOAP/SSO using C#

Which is the easiest way to consume a WSDL SOAP/SSO using C# ?
This is a third party system and i get this response:
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length
<?xml version="1.0" encoding="utf-8"?>
<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>
<RetornaEstadosPorMarcaResponse xmlns="http://WebService-MultiLogin-2013/">
<RetornaEstadosPorMarcaResult>
<EstadosMDL>
<ID>int</ID>
<Nome>string</Nome>
<Sigla>string</Sigla>
</EstadosMDL>
<EstadosMDL>
<ID>int</ID>
<Nome>string</Nome>
<Sigla>string</Sigla>
</EstadosMDL>
</RetornaEstadosPorMarcaResult>
</RetornaEstadosPorMarcaResponse>
</soap:Body>
</soap:Envelope>
And this is how i'm calling it:
public AdminMaster.RetornaEstadosPorMarca.Estados ssoEstados = new AdminMaster.RetornaEstadosPorMarca.Estados();
ssoEstados.RetornaEstadosPorMarca(Library.Configuracoes.ChaveSSO, Convert.ToInt16(Library.Configuracoes.Marca));
I have already tried to receive it as a string and format it to use as XML but it didn't work because of <soap:Body> and <soap:Envelope>, i get an error because i have the ':' on the name and i don't think that's the easiest way to do it.
So, how do i access the information from the response ? Is there another way ?
EDIT:
After several hours and tests i finally found the problem, "my" SOAP also gives me a class to create a object to receive the response, i only had to use it:
//Here i have the object with the methods
private Library.ssoEstados.Estados objEstadosSSO = new Library.ssoEstados.Estados();
//Here i have the object to receive the response
private Library.ssoEstados.EstadosMDL[] objEstadosMDL;
Than it was only a matter of read the values i wanted and send it to my own object.

XmlDocument xDoc = new XmlDocument();
xDoc.LoadXml(inputXml);
XmlNamespaceManager namespaces = new XmlNamespaceManager(xDoc.NameTable);
namespaces.AddNamespace("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");
namespaces.AddNamespace("ns2", "http://tempuri.org/");
XmlNode accountNode = xDoc.SelectSingleNode("/soapenv:Envelope/soapenv:Body/ns2:RetornaEstadosPorMarcaResponse/RetornaEstadosPorMarcaResult", namespaces);
XmlNode xnlAccount = accountNode.ChildNodes[0];
if (xnlAccount != null)
{
XmlDocument xAccount = new XmlDocument();
xAccount.LoadXml(xnlAccount.InnerText);
}
inputXml is a string containing your response xml.

Customize XML Serialize With new Tags And Attributes And Root

This is my Type:
public class MyObject {
public string destAdd { get; set; }
public long Time { get; set; }
public int maxNumb { get; set; }
public Account AccountCredentials { get; set; }
public System.String Serialize() {
String result = "";
XmlSerializer xs = new XmlSerializer(typeof(MyObject));
MemoryStream ms = new MemoryStream();
xs.Serialize(ms, this);
result = System.Text.Encoding.UTF8.GetString(ms.ToArray());
ms.Close();
ms.Dispose();
xs = null;
return result;
}
public static MyObject DeSerialize(String s) {
MyObject result = new MyObject();
XmlSerializer xs = new XmlSerializer(typeof(MyObject));
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(s));
result = (MyObject)xs.Deserialize(ms);
ms.Close();
ms.Dispose();
xs = null;
return result;
}
}
Then I serialize it like this:
MyObject obj = new MyObject();
obj.destAdd = "Destination";
obj.maxNumb = 99;
obj.Time = 128;
obj.Account = new Account { username = "user", password = "pass" };
string seializeObj = obj.Serialize();
The result is:
<?xml version="1.0"?>
<MyObject xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<destAdd>Destination</destAdd>
<Time>128</Time>
<maxNumb>99</maxNumb>
<Account>
<username>user</username>
<password>pass</password>
</Account>
</MyObject>
But I need the following result:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:smag="http://targetaddress.com/">
<soapenv:Header>
<Account>
<username>user</username>
<password>pass</password>
</Account>
</soapenv:Header>
<soapenv:Body>
<smag:myobjinfos>
<destAdd>Destination</destAdd>
<Time>128</Time>
<maxNumb>99</maxNumb>
</smag:myobjinfos>
</soapenv:Body>
</soapenv:Envelope>
How can I implement the serialize to get this result? any suggestion?

It appears that you are trying to call a web service, with a custom security header. Usually, the easiest way to do this would be to generate a set of proxy classes from the WSDL of the target webservice.
Either
Right click on the use Add Service Reference / Add Web Reference from the Visual Studio
Or, if you have the WSDL and xsd files of the service, then use wsdl.exe command line tool (e.g. wsdl.exe *.wsdl *.xsd //language:c#)
See here on how to set security information on the ws:security header
However, if you are 100% sure that you need to obtain the exact soapEnv Xml above, I would suggest you keep your code 'as is' (i.e. just serialize MyObject in its default format using XmlSerializer or DataContractSerializer), and then use a XslCompiledTransform.
This XSLT will do exactly this:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="/MyObject">
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:smag="http://targetaddress.com/">
<soapenv:Header>
<Account>
<username><xsl:value-of select="Account/username"/></username>
<password><xsl:value-of select="Account/password"/></password>
</Account>
</soapenv:Header>
<soapenv:Body>
<smag:myobjinfos>
<destAdd><xsl:value-of select="destAdd"/></destAdd>
<Time><xsl:value-of select="Time"/></Time>
<maxNumb><xsl:value-of select="maxNumb"/></maxNumb>
</smag:myobjinfos>
</soapenv:Body>
</soapenv:Envelope> </xsl:template>
</xsl:stylesheet>
Converts
<?xml version="1.0"?>
<MyObject>
<destAdd>Destination</destAdd>
<Time>128</Time>
<maxNumb>99</maxNumb>
<Account>
<username>user</username>
<password>pass</password>
</Account>
</MyObject>
To this:
<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:smag="http://targetaddress.com/">
<soapenv:Header>
<Account>
<username>user</username>
<password>pass</password>
</Account>
</soapenv:Header>
<soapenv:Body>
<smag:myobjinfos>
<destAdd>Destination</destAdd>
<Time>128</Time>
<maxNumb>99</maxNumb>
</smag:myobjinfos>
</soapenv:Body>
</soapenv:Envelope>
