WebService methods always return null

[Jan Obrestad]

I'm developing an application that uses a webservice.
It was working fine a few month ago, but going back to the project after
a couple of months on other projects, the code is suddenly not working.

ex
string q = "qry=John+smith";
try
{
string a = tlf.search(q);
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}

In this code fragment, tlf is the generated proxy to the web-service.

The problem is that a is null whatever I specify as the query. I have
used a packet sniffer to look at the actual packages sent, and they
contain the appropriate data.

Does anyone have an idea as to what could make this data to disappear?
I have contacted the ones making the web-service and they claim to have
made no major changes lately.

Hi Jan,

Try to guess.... has web method signature been changed last time? Common
error in this case is WSDL on client doesn't correspond the end-point's one.
