DocuSign Connect Listener MVC5 Api - asp.net-mvc

Question

I have the following MVC 5 Rest Controller:
namespace Rest4.Controllers
{
public class DocuSignController : ApiController
{
// POST api/docusign
public void Post([FromBody]DocuSignAPI.DocuSignEnvelopeInformation DocuSignEnvelopeInformation)
{
try
{
System.Xml.Serialization.XmlSerializer ser = new System.Xml.Serialization.XmlSerializer(typeof(DocuSignAPI.DocuSignEnvelopeInformation));
XmlSerializer serializer = new XmlSerializer(typeof(DocuSignAPI.DocuSignEnvelopeInformation));
StringBuilder sb = new StringBuilder();
using (StringWriter writer = new StringWriter(sb))
{
serializer.Serialize(writer, DocuSignEnvelopeInformation);
}
string fileName = DateTime.Now.Ticks.ToString();
using (StreamWriter outputFile = new StreamWriter(string.Format(#"c:\clientuploads\{0}.xml", fileName)))
{
outputFile.WriteLine(sb.ToString());
outputFile.WriteLine("Nothing to see here");
}
}
catch { }
}
However, when I go to the DocuSign Connect Settings and try to send the same, all I get is:
<?xml version="1.0" encoding="utf-16"?>
<DocuSignEnvelopeInformation xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:nil="true" />
Nothing to see here
However, if I look at the logs on the DocuSign site:
1/28/2016 8:49:56 PM Connect send to: http://somewhere.com/Rest/api/DocuSign
1/28/2016 8:49:56 PM Envelope Data (documents were included):<?xml version="1.0" encoding="utf-8"?><DocuSignEnvelopeInformation xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.docusign.net/API/3.0"><EnvelopeStatus><RecipientStatuses><RecipientStatus><Type>Signer</Type><Email>someemailaddress</Email><UserName>somebody</UserName><RoutingOrder>1</RoutingOrder><Sent>2016-01-13T10:35:11.16</Sent>....<Sequence>4</Sequence></DocumentStatus></DocumentStatuses></EnvelopeStatus></DocuSignEnvelopeInformation>
So, why is the document I get from DocuSign empty? Is there a better way to capture the info? If I try Post([FromBody]string DocuSignEnvelopeInformation) instead, I get a 500 Error on the DocuSign site

Did you specify the default name space while initializing serializer as follows.
XmlSerializer serializer = new XmlSerializer(typeof(DocuSignEnvelopeInformation), "http://www.docusign.net/API/3.0");
DocuSignEnvelopeInformation envelopeInfo = serializer.Deserialize(reader) as DocuSignEnvelopeInformation;
