Why aren't those options? It shouldn't matter how you create the cert, as long as you have one...
...except that the normal System.Net stack wants a "valid" certificate chain lest it start throwing exceptions, and it'll start throwing exceptions with your self-signed cert.
The workaround for this is to set the System.Net.ServicePointManager.ServerCertificateValidationCallback property [0, 1] to a delegate which will check that the certificate you're getting from the server matches what your app expects. If it does, it can return `true` and the certificate will be used anyway, allowing you to use a self-signed cert. If the delegate returns `false`, the connection will be refused, as normal.
