X509Certificate2.PrivateKey is obsolete. Use a method such as GetRSAPrivateKey() or GetECDsaPrivateKey(). Alternatively, use the CopyWithPrivateKey() method to create a new instance with a private key. Further, if you set X509Certificate2.PrivateKey to `null` or set it to another key without deleting it first, the private key will be left on disk.
