Set a TLS Client Certificate from a PFX

Demonstrates Socket.SetSslClientCertPfx, which loads and configures a TLS client certificate and private key from a PFX/P12 file.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Background. Configure the client certificate before connecting. Use client certificates only when the server requests or requires client-certificate authentication (mutual TLS).
