Could not establish secure channel for SSL/TLS with authority '*'

Question

I must consume a PHP webservice which has a SSL certificate. My .net 3.5 Class library references the webservice with \'Add Service references\' in Visualstudio 2010 (WCF ri

Answer 1

In case it helps anyone else, using the new Microsoft Web Service Reference Provider tool, which is for .NET Standard and .NET Core, I had to add the following lines to the binding definition as below:

binding.Security.Mode = BasicHttpSecurityMode.Transport;
binding.Security.Transport = new HttpTransportSecurity{ClientCredentialType = HttpClientCredentialType.Certificate};

This is effectively the same as Micha's answer but in code as there is no config file.

So to incorporate the binding with the instantiation of the web service I did this:

 System.ServiceModel.BasicHttpBinding binding = new System.ServiceModel.BasicHttpBinding();
 binding.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.Transport;
 binding.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Certificate;
 var client = new WebServiceClient(binding, GetWebServiceEndpointAddress());

Where WebServiceClient is the proper name of your web service as you defined it.
