Answer by Chris W. Rea for Managing HTTPS server certificates from inside a program?

Have a look at the System.Security.Cryptography.X509Certificates namespace.

Notably, the X509Store class will do at least one of the things you're referring to: Importing an existing certificate into the store. e.g.

X509Store store = new X509Store(StoreName.Root, StoreLocation.LocalMachine);try{ store.Open(OpenFlags.ReadWrite); store.Add(     new X509Certificate2(@"Certificates\MyCertificate.pfx", "password"));}finally{ store.Close();}

On one of your other parts, creating a certificate, I found this: makecert.cs: makecert clone tool ... if you're not going to call out to a console tool like makecert.exe, you'll likely end up implementing something similar to that.
