Invoking WCF client from Excel VBA

Has anybody try to invoke a WCF (.NET 3.0) web service client
from unmanaged code (and especially from Excel VBA) ?

When I tried it I got:
--cut here--
An error occured creating the configuration section handler for

system.serviceModel/client: That assembly does not allow partially

trusted callers.
--cut here--

It has probably something to do with .NET 3.0 security model
and I suppose it is somehow configurable.

Any ideas ?

WCF V1 does not support partially trusted callers. Dominick Baier came up
with a workaround:
