ASP.NET SOAP Server/Client with Complex Types

Trying to build a SOAP web service using complex types and hit a road block. I am using VS to create a web reference to the SOAP service. ASP.NET 2.0, C#.

Getting the following error on the client:
System.NullReferenceException: Object reference not set to an instance of an object.
On the line setting the name on the SOAP client below, info.Organization.Name = "Test Org";

Here is what I have so far:

SOAP Web Service

public string CoverageRequest(RequestorInformation info)
      return info.Organization.Name;

public class RequestorInformation
      public Organization Organization;

public class Organization
      public Organization() {}

      private string _Name;
      public string Name
            get { return _Name; }
            set { _Name = value; }

SOAP Client

VerifyInsurance.RequestorInformation info = new VerifyInsurance.RequestorInformation();
info.Organization.Name = "Test Org";

VerifyInsurance verify = new VerifyInsurance();

Organization is a class and it is not instantiated. Try:
VerifyInsurance.RequestorInformation info = new VerifyInsurance.RequestorInformation();
info.Organization = new Organization();
info.Organization.Name = "Test Org";

The way to verify that the line below is missing, is to put a breakpoint and check the organization class values in the debugger.

Happy new year,
