This works better, but now the next problem rears it's ugly head. The app.config for WCF is not used. So I need to configure the proxy class to use a certificate. For WCF I just say</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt; &lt;configuration&gt; &lt;system.serviceModel&gt; &lt;bindings&gt; &lt;basicHttpBinding&gt; &lt;binding name="TestBinding"/&gt; &lt;/basicHttpBinding&gt; &lt;/bindings&gt; &lt;client&gt; &lt;endpoint address="https://demo.blablablablablabla.com:123/Bla" binding="basicHttpBinding" bindingConfiguration="TestBinding" contract="MissileDefenseSystemServiceReference.TestPortType" name="TestPort"&gt; &lt;identity&gt; &lt;certificateReference storeLocation="CurrentUser" x509FindType="FindByThumbprint" findValue="the thumbprint to be used" /&gt; &lt;/identity&gt; &lt;/endpoint&gt; &lt;/client&gt; &lt;/system.serviceModel&gt; &lt;/configuration&gt; </code></pre> <p>OK, now using a piece of code to provide signatures</p> <pre><code> proxy.ClientCertificates.Add(cert); </code></pre> <p>This now almost works, except it can't decode the response.</p>
