At first you should import certificate and then attach to request

X509Certificate2 certificate = new X509Certificate2();
certificates.Import(...);

client.ClientCertificates = new X509CertificateCollection(){certificate};

So this did indeed work, however when I send the request the certificate is not on it. Despite verifying the clients certificate collection is populated with my -self-signed- cert – Chazt3n Mar 03 '16 at 22:51
OK I definitely did this, now I'm sending the certificate across the wire. Thanks for the edit. Do you happen to know the minimum requirements for accepting a client certificate in WebAPI? – Chazt3n Mar 07 '16 at 16:09
