Getting the certificate info from the request on Restful POST - wcf

Question

Hi I am having a Restful service (DotNet 4.0 WCF VS 2012) in HTTPS. My client will attach a certificate to it (certificate is given by me (.cer file)) I need to get the certificate back from the request and read its information to authenticate it, The serial Number, Thumprint are stored in DB when I need to check the same.
I did the SSL and Share the cer file to the client.
I used the following code to read back my certificate
C# code start
if (OperationContext.Current.ServiceSecurityContext.AuthorizationContext.ClaimSets == null)
throw new Exception ("No claimset service configured wrong");
if (OperationContext.Current.ServiceSecurityContext.AuthorizationContext.ClaimSets.Count <= 0)
throw new Exception ("No claimset service configured wrong");
var cert = ((X509CertificateClaimSet)OperationContext.Current.ServiceSecurityContext.
AuthorizationContext.ClaimSets[0]).X509Certificate;
C# code end
in the above code i always gets claimSets.Count = 0.
Is any setting I need to do in my server web.config, I did the following setting in my Server Side web.config
'security mode="Transport"'
'transport clientCredentialType="None"'
'security'
Please let me know Is I am missing any settings in the client side or the server side.
In the client side I am using following code the add the cer to the request
C# Code Start
X509Certificate2 cert = new X509Certificate2 ("C:\\xxxxxx.cer");
System.Net.ServicePointManager.ServerCertificateValidationCallback =
delegate(Object obj, X509Certificate X509certificate, X509Chain chain, System.Net.Security.SslPolicyErrors errors)
{
return true;
};
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(xxxxx.Text.Trim());
webRequest.ClientCertificates.Add(cert);
C# Code End
I did not have any special setting in my client web.config file.

Why you use clientCredentialType="None" and not clientCredentialType="Certificate"?
It is also possible your client does not send any certificate. Try to enable Network Tracing in App.config on the client - instructions here. That should create network.log with more debug info. Look for SecureChannel entries in log.
