How to generate Rijndael KEY and IV using a passphrase?

Other answers contain way more information. The answer to this question where you only want to generate the key and IV given a passphrase use:

        // use something more random in real life
        var salt =  new byte[]{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16};

        string password = "my-password";
        Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(password, salt);
        var key = pdb.GetBytes(32);
        var iv = pdb.GetBytes(16);
