i think that WSDL generation may be broken, or at least incompatible with C# implementation of it as when trying to consume SOAP 1.1 from C#, any array will have null value even if Ladon will actually send some XML data.
i have seen another bug reported here telling that WSDL Array are broken, BTW the provided patch do not help, i think this is still broken and may be inner elements should be contained inside specific node rather than in "item" ?
here is how to reproduce this from the AlbumService example provided :
1/ from any Visual Studio project, as Console Application, first create a Service Web reference like explained here : http://webservices20.blogspot.fr/2008/10/interoperability-gotcha-visual-studio.html for this example called 'albumsWR'
2/ code for the C# apps

using System.Collections;

using System.IO;
using System.Linq;

using ConsoleApplication6.albumsWR; // PUT HERE THE NAME OF THE "Web References" you provide @ step 1
namespace ConsoleApplication6
{
class Program
{
static void Main(string[] args)
{
AlbumService albumService = new AlbumService();
var filteredAlbums = albumService.listAlbums("The");
if (filteredAlbums.item == null)
{
Console.WriteLine("null contained, while it should not!");
}
}
}
}

when checking the result with SOAP UI, of course an XML result is provided, if we intercept the data sent with Fiddler to the C# program here is what is provided so one can check that is not a 'null' answer, BTW may be some inconsistencies occurs between the WSDL definition and/or namespace and the result provided, that prevent C# to understand how to unserialize the result ?

here is a cut n paste of this interception with Fiddler (that is the raw Ladon answer to the C# call)
