Values for storeLocation are included in the StoreLocation enumeration:

  • LocalMachine: the certificate store assigned to the local machine (default).

  • CurrentUser: the certificate store used by the current user.

If the client application is running under a system account, then the certificate is typically in LocalMachine. If the client application is running under a user account, then the certificate is typically in CurrentUser.

Values for storeName are included in the StoreName enumeration.

The following code specifies the certificate to use.

// Create a WSHttpBinding and set its security properties. The
// security mode is Message, and the client is authenticated with 
// a certificate.
EndpointAddress ea = new EndpointAddress("http://contoso.com/");
WSHttpBinding b = new WSHttpBinding();
b.Security.Mode = SecurityMode.Message;
b.Security.Message.ClientCredentialType =

// Create the client with the binding and EndpointAddress.
CalculatorClient cc = new CalculatorClient(b, ea);

// Set the client credential value to a valid certificate.
