I need to communicate with a third party which has a .asmx web service. This web service is using https. I have the required certificate (.pfx).
When first trying to add this service using Add Service Reference in Visual Studio, I got an error. I got passed this error by importing the certificate into the Personal store. After I did that, I tried to add the Service Reference again and it works. So now I can create an instance of the web service. Nice.
But now I want to invoke the service. And when I do that I get this error:
302 Notification: Digital Certificate Missing
So how can I tell my service to use the right certificate?
I finally managed to fix my problem as follows:
var service = new Service1SoapClient();
service.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.TrustedPublisher, X509FindType.FindByIssuerName, "name_of_issuer");
((BasicHttpBinding)service.Endpoint.Binding).Security.Mode = BasicHttpSecurityMode.Transport;
((BasicHttpBinding)service.Endpoint.Binding).Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
If any have problems with references you need add. using System.Security.Cryptography.X509Certificates
