This namespace is available when you reference the Tweetinvi.Core dll.
In theory you must have this dll referenced to use Tweetinvi as all the other dll references it.
Have you taken the dll's from nuget?
By the way I can see that you are trying to get 220000 followers, please note that you will check your rate limits to get this number of followers.
