web services - 'Error serializing body'. Problem calling Fedex webservice through .NET 3.5

Question

I'm using Fedex's web services and getting an annoying error right up front before I can actually get anywhere.

There was an error in serializing body of message addressValidationRequest1: 'Unable to generate a temporary class (result=1). error CS0030: Cannot convert type 'FedEx.InterOp.AddressValidationServiceReference.ParsedElement[]' to 'FedEx.InterOp.AddressValidationServiceReference.ParsedElement' error CS0029: Cannot implicitly convert type 'FedEx.InterOp.AddressValidationServiceReference.ParsedElement' to 'FedEx.InterOp.AddressValidationServiceReference.ParsedElement[]' '. Please see InnerException for more details.

I'm using .NET 3.5 and get a horrible named class generated for me (I'm not sure why it isn't just AddressValidationService):

AddressValidationPortTypeClient addressValidationService = new ...;

on this class I make my web service call:

addressValidationService.addressValidation(request);

This is when I get this error.

The only references I can find to this error come from ancient 1.1 projects. In my case my DLL has references to System.Web and System.Web.Services which seemed to be an issue back then.

You only need change the [][], not the single [].

In Reference.cs change

private ParsedElement[][] parsedStreetLineField;
to
private ParsedElement[] parsedStreetLineField;
and
public ParsedElement[][] ParsedStreetLine {
to
public ParsedElement[] ParsedStreetLine {
