WCF: Passing Windows-credentials to service

[Jesper Lund Stocholm]

I have created a WCF-service running on IIS. The virtual directory has
anonymous access disabled and requires integrated windows authentication.

The proxy to the service is auto-generated using Visual Studio 2008's
"Add Service reference".

My problem is that when I try to execute a method on the service, I get
the following exception:

The HTTP request is unauthorized with client authentication scheme
'Anonymous'. The authentication header received from the server was
'Negotiate,NTLM'

How do I solve this? I can't seem to get my head around passing the
correct windows-credentials to my channel, so any help will be greatly
appreciated.

My instatiation of my client in code is this:

BWServiceClient BWClient = new BWServiceClient();

List<BathingwaterStationlist = new List<BathingwaterStation>();
list.AddRange(
BWClient.GetBathingWaterStationList(
year_, stationNumber_, stationName_, municipalityCode_
)
);

Thanks,
