New Post: Hey I missing a .dll?

I trying test out some queries example , but I can't do without this namespace

Tweetinvi.Core.Interfaces.DTO.QueryDTO

Example:

 var credentials = TwitterCredentials.CreateCredentials(access_Token, access_Token_Secret, consumer_Key, consumer_Secret);
           
             TwitterCredentials.ExecuteOperationWithCredentials(credentials, () =>
        {
            var followerQuery = String.Format("https://api.twitter.com/1.1/followers/ids.json?user_id={0}", 111111111);
            var returnedIds = TwitterAccessor.ExecuteCursorGETQuery<IIdsCursorQueryResultDTO>(followerQuery, 220000)
                .SelectMany(x => x.Ids);  }
         }

Error 2 The type or namespace name 'QueryDTO' does not exist in the namespace 'Tweetinvi.Core.Interfaces.DTO' (are you missing an assembly reference?)

Error 3 The type or namespace name 'IIdsCursorQueryResultDTO' could not be found (are you missing a using directive or an assembly reference?)
