I'm working on changing our app to use HttpClient instead of WinHttp.WinHttpRequest for web api calls.

My question has to do with client side certificates. Our current code has this:

io_winhttpRequest.SetClientCertificate(is_certificate)

The HttpClient function is quite different:

SetClientCert(string p12cert, string password)

p12cert - The client's private key and public key p12 or PFX certificate file path.
password - Password of p12 or PFX certificate.

SetClientCert(string storeName, string certIssue, string certSN)

storeName - A string that specifies the name of the certificate store. Valid values are: MY, Root, Trust, CA.
certIssue - A string that identifies the entity that has signed and issued the certificate.
certSN The serial number of the certificate.

What we are passing to SetClientCertificate is a registry key. Whether any customers are using this feature, I don't know. The web api is usually one of our  servers on the same network.

Any ideas would be helpful.
