Does the Certificate Services Library support creating Certificates, or only parsing them? What function would I use to create one?

Thanks!

The library currently only parses certificates. There is no way to generate a certificate.
We're thinking of adding this functionality to one of the next versions of the library [as you can see in AssemblyInfo.cs, it's on our TODO list].

In the mean time you can use Microsoft Certificate Server to create certificates. Certificate Server comes with the Server editions of Windows.
Alternatively, you can use OpenSSL to generate your certificates [www.openssl.org].
