Anyone knows how to force the WebBrowser control to automatically select a specific client certificate and not open the pop up with client certificates list?
回答1:
I solved this issue changing the certificate purposes to "Disable all purposes for this certificate", so just the certificate with the desired purpose could be used by WebBrowser control.
