Issue while generating a service proxy from WSDL with invalid SSL Certificate

I'm trying to write a small app that accesses a webservice, but the webservice has an invalid SSL certificate. I've got no control over this fact as it's governed by a third party.

I've tried accessing the site via IE (As administrator and as my own user) and installing the certificate but it doesn't seem to do very much, as the next time I browse to it I get the same error.

When I run svcutil I get the following output:

C:\Personal>svcutil.exe https://b2b:9443/LiveFeed.svc?wsdl
Microsoft (R) Service Model Metadata Tool

Attempting to download metadata from 'https://b2b:9443/LiveFeed.svc?wsdl' using

Error: Cannot obtain Metadata from https://b2b:9443/LiveFeed.svc?wsdl

If this is a Windows (R) Communication Foundation service to which you have acce

ess.  For help enabling metadata publishing, please refer to the MSDN documentat

WS-Metadata Exchange Error
    URI: https://b2b:9443/LiveFeed.svc?wsdl

    Metadata contains a reference that cannot be resolved: 'https://b2b:9443/Liv
eFeed.svc?wsdl'.

    Could not establish trust relationship for the SSL/TLS secure channel with a
uthority 'b2b:9443'.

    The underlying connection was closed: Could not establish trust relationship
 for the SSL/TLS secure channel.

    The remote certificate is invalid according to the validation procedure.


HTTP GET Error
    URI: https://b2b:9443/LiveFeed.svc?wsdl

    There was an error downloading 'https://b2b:9443/LiveFeed.svc?wsdl'.

    The underlying connection was closed: Could not establish trust relationship
 for the SSL/TLS secure channel.

    The remote certificate is invalid according to the validation procedure.

If you would like more help, type "svcutil /?"

I know the issue is to do with the certificate being invalid, but I can't seem to make the certificate trusted. How would I go about doing this?

What I have done so far is click on the error, view the certificate, and install it. I've tried this in the certificate store that windows selects it's self and in the personal and trusted stores, none of this makes a difference.

Even if I manage to solve this I'm concerned that I'll run into issue when I install the application on my customers PC, given that we are in two different countries.

Any help would be appreciated.

  try this before calling the service..

  ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(
            delegate
            {
                return true;
            });

It may be as simple as installing the root CA certificate for the cert.
