WCF and code generation from WSDL

I am writing a "universal" client for Web services, and have hit an unexpected problem. I generate the code for the client dynamically by retrieving the Web services WSDL, and using the following (simplified a little) code to generate the client code:

ServiceDescription serviceDescription = ServiceDescription.Read(xmlTextReader(WSDL));
ServiceDescriptionImporter descriptionImporter = new ServiceDescriptionImporter();
descriptionImporter.ProtocolName = "Soap";
descriptionImporter.Style = ServiceDescriptionImportStyle.Client;
CodeCompileUnit codeCompileUnit = new CodeCompileUnit();
CodeDomProvider codeDomProvider = CodeDomProvider.CreateProvider("CSharp");
codeDomProvider.GenerateCodeFromCompileUnit(codeCompileUnit, Console.Out, new CodeGeneratorOptions());

I am testing this using a simple WCF Web service that exposes two methods:

[OperationContract]
int GetInteger();

[OperationContract]
string GetString();

If I examine the client-side generated code, then I can see that the GetString() returns a string, but the GetInteger() method returns void! I assume that this is something to do with value and reference types. Is there some way to force the code generator to make the GetInteger() method return an int?

From various experiments, I believe that my problem is an inherent limitation of using the ServiceDescriptionImporter to generate the client code. I am going to try to "upgrade" to using the System.ServiceModel.Description.WsdlImporter and System.ServiceModel.Description.ServiceContractGenerator framework, in the hopes that improves things.

Returning an int over WCF should not be a problem.

Check the code that produces the client side generated code.

The hack to get around the problem would be to return an object that had a single property that was an int.
