Web Service returning NULL

Algobardo

Good morning,
this is the first time i write on this forum because i googled and i've seen related post with no solution.

I will expose briefly the problem.
I'm using c# 3.5 and i'm trying using a web service.
Unfortunatly i get a NULL response and i can't understand why.

RpcRsat.RSATWSPortType rpt = new RpcRsat.RSATWSPortTypeClient();
RpcRsat.retrieve_seqResponse res = rpt.retrieve_seq(req);

res is NULL.

I've seen that this problem is a naming related problem so i think that if i post both the wsdl and server request/answer would be possible to correct the wsdl to have a not null answer.

The wsdl of the service
