title: SSL Client Authentication with certificate using c#
body: <p>I need to create a c# application that has to send API request to a server using SSL. I need to create the Client authentication. I already have the server CA certificate, the client certificate (cer), the client private key (pem) and passphrase. I can't find an example on how to create the client connection. Can someone suggest me where to start with a small code well explained? In my hand I have the client certificate (PEM), the Client Provate Key and the Passphrase for the Client Key. I have no idea where to start to write the code to send a request to the server</p>
