We have a client application that communicates with a SOAP service that requires mutual authentication. Our customer uses a certificate and private key from a smart card to access the SOAP service and have been using it without a problem in Windows 7 for some time now. They have recently upgraded to Windows 10 and the smart card authentication no longer works. The first attempt to access the SOAP service works fine but all subsequent requests to the SOAP service fail with "Could not create SSL/TLS secure channel"
The client application uses the standard auto generated SOAP classes and we add the client certificate to the list of client certificates in SoapHttpClientProtocol.
Please help!
