I'm trying to download some twitter info asynchronously and it's blocking the UI thread. I'm using LinqToTwitter (http://linqtotwitter.codeplex.com/) to download the info.

Here's the call to the task

```
PublicTweetListBox.ItemsSource = await getTweets(twitterCtx);

```

And here's the task itself

```
async Task<List<TweetViewModel>> getTweets(TwitterContext twitterCtx)
{       
    var tweetList = await Task.FromResult<List<TweetViewModel>>(
    (from tweet in twitterCtx.Status
    where tweet.Type == StatusType.User
    && tweet.ScreenName == UserName.Text
    select new TweetViewModel
    {
        Name = tweet.User.Name,
        Tweet = tweet.Text,
        ImageUrl = tweet.User.ProfileImageUrl
    })
    .ToList());

    return tweetList;

}

```

I'm doing something wrong in the way I await downloading the list, TweetViewModel is a custom type if that helps.
