fb.Get() doesn't exist?

问题

I have the code below that I got from off of Prabir's Blog (codeplex documentation) and the fb.get() method does not exist...I was able to test all the way up to authentication where it takes me to the fb login page and now I am trying to do the fb.Get("/me"); I am new to this and am just following the guide...

private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
    string appId = "xxx";
    string[] extendedPermissions = new[] { "publish_stream", "offline_access" };

    var oauth = new FacebookOAuthClient { AppId = appId};

    var parameters = new Dictionary<string, object>
    {
        { "response_type", "token" },
        { "display", "popup" }
    };

    if (extendedPermissions != null && extendedPermissions.Length > 0)
    {
        var scope = new StringBuilder();
        scope.Append(string.Join(",", extendedPermissions));
        parameters["scope"] = scope.ToString();
    }

    var loginUrl = oauth.GetLoginUrl(parameters);

    webBrowser.Navigating += webBrowser_Navigated;
    webBrowser.Navigate(loginUrl);
}

private void webBrowser_Navigated(object sender, NavigatingEventArgs e)
{
    FacebookOAuthResult result=null;

    if (FacebookOAuthResult.TryParse(e.Uri, out result))
    {
        if (result.IsSuccess)
        {
            var accesstoken = result.AccessToken;
            var fb = new FacebookClient(accesstoken);

            var results = (IDictionary<string, object>)fb.Get("/me");
            var name = (string)results["name"];

            MessageBox.Show("Hi " + name);
        }
        else
        {
            var errorDescription = result.ErrorDescription;
            var errorReason = result.ErrorReason;
        }
    }
}

use fb.GetAsync instead. Window Phone 7 doesn't support synchronous methods.

i highly recommend you to download the source code and checkout the "Samples\CS-WP7.sln" example.

var fb = new FacebookClient(_accessToken);

fb.GetCompleted += (o, args) =>
                       {
                           if (args.Error == null)
                           {
                               var me = (IDictionary<string, object>)args.GetResultData();

                               Dispatcher.BeginInvoke(
                                   () =>
                                   {
                                       FirstName.Text = "First Name: " + me["first_name"];
                                       LastName.Text = "Last Name: " + me["last_name"];
                                   });
                           }
                           else
                           {
                               Dispatcher.BeginInvoke(() => MessageBox.Show(args.Error.Message));
                           }
                       };

fb.GetAsync("me");
