NServiceBus Deserialization Exception After Deployment

Question

I am currently using NServiceBus6. I am successfully submitting a message from my web api to endpoint which is windows service hosted. Everything works fine in my development environment on my local machine. I am using "NewtonsoftSerializer" in all my endpoint configurations. I have now deployed my solution to a server. My services are now hosted as Window Services as opposed to a console app. Service Insight is now reporting an NServiceBusDeserialization Exception:

An error occurred while attempting to extract logical messages from transport message 8221d498-81ca-406e-8ab6-a77701065f1f ---> System.Xml.XmlException: Data at the root level is invalid. Line 1, position 1.

A couple items stick out. A. I am not using XmlSerialization. B. I have no serialization issues in development environment. I would appreciate any help provided thank you.

Message Class:

 public class CreateSearchRequest : ICommand
{
    public SearchRequest Request { get; set; }
}

SearchRequest:

 public class SearchRequest : Resource
{
    public string User { get; set; }
    public string SearchName { get; set; }
    public SearchCriteriaSimple Criteria { get; set; }
    public string Status { get; set; }
    public DateTime RequestBegin { get; set; }
    public DateTime RequestEnd { get; set; }
    public int Records { get; set; }
    public string OutputFileName { get; set; }
    public string FtpLocation { get; set; }
    public DateTime CreateDate { get; set; }
}

SearchRequestSimple:

 public class SearchCriteriaSimple
{
    public string Name { get; set; }
    public List<Dictionary<string, string>> Criteria { get; set; }
}

Answer 1

I am embarrassed to say. But I have figured out the issue. During development in Visual studio I configured the endpoint in the Task AsyncOnStart() method of ProgramService.cs. It seems once I install the NServiceBus host I must also provide configuration via Endpoint Config. Once I matched serialization there the issues went away.
