Google apps Directory API (1.6 and above) DotNetOpenAuth not resolving - google-api

Question

This code is changing fast and hard to get a handle on what works and what doesn't...
I was looking at this post: Have you used Google's Directory API?
Which is using the 1.4 library.
I installed the 1.6 API through nuget. However, the NativeApplicationClient and IAuthorizationState cannot be resolved. I was under the impression that I no longer needed the DotNetOpenAuth nuget package or the Google.Apis.Authentication package (which is where I believe they are resolved.
This is the complete and modified code I am playing with: (if you have a better example of creating users using the new API I'd like to see that!)

From release 1.6.0-beta we presented a new Google.Apis.Auth NuGet package (Google.Apis.Authentication which uses DNOA is obsolete!). You already installed that package, because all the new APIs have a reference to it. Take a look in our OAuth2 wiki page for more details about how to use the new OAuth2 flows (it's not magic anymore, now the flows actually make sense!)
I recommend you subscribing to our announcement blog and optionally to my personal blog to get more information about the client library. In our announcement blog we described the reason the new OAuth2 pacakge.
Hope it is helpful.
