Getting WSDL descriptions securely

As I said in a comment on #3318 ...

That solves the problem once the client is generated ...
How did you solve the issue of getting the WSDL description in the first place with a client cert?

I can't find an answer to this anywhere.

Since this ticket is long closed I figured I ask here instead:

I've been given an SSL cer file and told "here's the URL to our service, add ?wsdl to the end to get the metadata endpoint", but I can't figure out how in the VS UI to get the WSDL description, so I wrote some code to do it and i'm getting a TLS handshake error from the service.

I've raised the question about the error from the server with the service provider but I was hoping there was a built in way to get this.

How do I get the WSDL for a secure service that can only be communicated with using client cert?
