Windows Phone 7 Sample using Facebook SDK for .NET

Facebook C# SDK Sample with Windows Phone 7

This sample demonstrates the use of Facebook C# SDK v6 as a Windows Phone 7 Application.

Note: This sample does not necessarily demonstrate the best use but rather features of using Facebook C# SDK on a Windows Phone 7 app. Always remember to handle exceptions.

Getting started

Set the appropriate AppId in FacebookLoginPage.xaml.cs before running the sample.

private const string AppId = "app_id";

Note:

• For new projects using Facebook C# SDK which use anonymous objects as parameters make sure to add [assembly: InternalsVisibleTo("Facebook")] in AssemblyInfo.cs.
• When updating UI in callback make sure to execute it in the appropriate thread. This can be solved by using Dispatcher.Invoke() method.
• Create new instance of FacebookClient for each XAsync method calls in order to avoid the event handler from being fired multiple times.

certificate error

hi,

when i start the sample projects i always get a certificate error:

how to fix this problem?
cheers

Back navigation

If you hit the button "Login To Facebook" then the page with the facebook login UI loads.
Then when i hit the back button on my phone i get a black screen and a error message then when i hit back again i'm seeing the MainPage.xaml. Now the "Login To Facebook" button does not show the login UI but gives a direct error message.

Not Implemented Exception thrown when using Windows phone 8.1 SDK

I am working through the samples for login on the facebooksdk.net site and have the sample for login working for a Windows store app working as expected.

I cannot get the sample for a Windows Phone app to work properly, however. When I follow the sample, I have to first modify the XAML namespace sample from: xmlns:facebookControls="clr-namespace:Facebook.Client.Controls;assembly=Facebook.Client" to xmlns:facebookControls="using:Facebook.Client.Controls". This is the same as it is for the Windows Store application and prevents a compilation error in VS 2013 from occurring. Even after doing this, I do NOT see the login button appear in the designer as I do for the Windows app. At runtime the button does appear in the emulator or on a device. When clicking the Facebook login button a “Not Implemented Exception” is thrown from deep in the stack which appears to be coming from Facebook.Client.FacebookSessionClient as can be seen in this stack trace:

I am wondering if this is something that is known and if there is a work around for this issue? Here are the versions of the NuGet packages that I am currently using:
Facebook: 6.0.10.0
Facebook.Client: 0.9.1.0
Visual Studio 2013 R3 with .NET 4.5.1

This property is not implemented by this class. Error in my project.

I am following Your Instructions. It was working in my sample project. When i try to implement in my original project i get error.

private void LoginSucceded(string accessToken)
{
var fb = new FacebookClient(accessToken);

        fb.GetCompleted += (o, e) =>
        {
            if (e.Error != null)
            {
                Deployment.Current.Dispatcher.BeginInvoke(() =>
                {
                    MessageBox.Show(e.Error.Message);
                    return;
                });
            }

            var result = (IDictionary<string, object>)e.GetResultData();
            var id = (string)result["id"];

            var url = string.Format("/Views/FacebookInfoPage.xaml?access_token={0}&id={1}", accessToken, id);
            var rootFrame = (App.Current as App).RootFrame;
            Deployment.Current.Dispatcher.BeginInvoke(() =>
               {
                   rootFrame.Navigate(new Uri(url, UriKind.Relative));
               });
        };

        fb.GetAsync("me?fields=id");
    }

In this method i am getting error in this line: fb.GetAsync("me?fields=id");
