Linq to Twitter Authenticated But Getting 215 "Bad Authentication Data"

Question

I have been using Linq to Twitter for Authenticating with OAuth for the Twitter API 1.1. I set my credentials and then pass them to Linq to Twitter which states I that isAuth returns true. However, at run time I receive at 215 "Bad Authentication Data" error. Has anyone else had this problem?

  var auth = new SingleUserAuthorizer
        {
            Credentials = new InMemoryCredentials
            {
                ConsumerKey = TwitterSettings.ConsumerKey,
                ConsumerSecret = TwitterSettings.ConsumerKeySecret,
                OAuthToken = TwitterSettings.AccessToken,
                AccessToken = TwitterSettings.AccessTokenSecret,
            }
        };
        auth.Authorize();
    }

And here is the if else that is stating I am authorized:

        if (auth == null || !auth.IsAuthorized)
        {

        }
        // If Twitter Authorizes Application 
        if (auth.IsAuthorized && i == 1)
        {

            HttpClient client = new HttpClient();
            HttpResponseMessage response = await client.GetAsync(new Uri("https://api.twitter.com/1.1/search/tweets.json?q=%23freebandnames&since_id=24012619984051000&max_id=250126199840518145&result_type=mixed&count=4"));
            string json = await response.Content.ReadAsStringAsync();

            JObject obj = JObject.Parse(json);
            var jsonResults = obj["results"];

            await JsonConvert.DeserializeObjectAsync<List<Tweet>>(jsonResults.ToString());

        }

I am able to get into the auth.IsAtuhorized portion of the code but the response is returning a 215 error. Also I know my URI is correct because I copied it straight from the Twitter API 1.1 example page to test the call. Thanks in Advance

You're using the authorizer properly, but then you aren't using LINQ to Twitter to make your query. You're using HttpClient instead and there isn't a relationship between the two APIs. Here's a example of how to perform a Search with LINQ to Twitter:

    var srch =
        (from search in twitterCtx.Search
         where search.Type == SearchType.Search &&
               search.Query == "LINQ to Twitter" &&
               search.Count == 7
         select search)
        .SingleOrDefault();

    Console.WriteLine("\nQuery: {0}\n", srch.SearchMetaData.Query);
    srch.Statuses.ForEach(entry =>
        Console.WriteLine(
            "ID: {0, -15}, Source: {1}\nContent: {2}\n",
            entry.StatusID, entry.Source, entry.Text));

You can visit the LINQ to Twitter Search Documentation for more info on available parameters.

Update, Here's an asynchronous sample:

    (from search in twitterCtx.Search
     where search.Type == SearchType.Search &&
           search.Query == QueryTextBox.Text
     select search)
    .MaterializedAsyncCallback(asyncResponse =>
        Dispatcher.BeginInvoke(() =>
        {
            if (asyncResponse.Status != TwitterErrorStatus.Success)
            {
                MessageBox.Show("Error during query: " + asyncResponse.Exception.Message);
                return;
            }

            Search search = asyncResponse.State.SingleOrDefault();
            var tweets =
                (from status in search.Statuses
                 select new Tweet
                 {
                     UserName = status.User.Identifier.ScreenName,
                     Message = status.Text,
                     ImageSource = status.User.ProfileImageUrl
                 })
                .ToList();

            SearchListBox.ItemsSource = tweets;
        }));

Thanks Joe. One more question though rather than writing the results the console using Write line I am trying to add them to a list. I've tried using the basic Foreach Loop and your srch.Statues.Foreach method but it keeps saying it does not contain a method for 'ForEach' — Dadles, May 08 '13 at 14:37
Never Mind was able to do a work around by performing a basic For Loop thanks for your help. Will Post the finished answer upon code completion — Dadles, May 08 '13 at 16:18
Joe. One more question is there anyway to use async and await with the search function to increase performance? — Dadles, May 09 '13 at 13:24
Dadles, I did an update to the post to show the asynchronous syntax that's available today. That said, async is something I'm looking at for a future set of enhancements. — Joe Mayo, May 09 '13 at 14:25
