Authentication

Initializing the Facebook Session

Set the Facebook App ID and Windows Store ID values in active session:

using winsdkfb;

namespace SampleCode
{
    public static partial class SampleFunc
    {
        static void Initialization()
        {
            FBSession sess = FBSession.ActiveSession;
            sess.FBAppId = "<Facebook App ID>";
            sess.WinAppId = "Windows or Windows Phone Store ID depending on target device";
        }
    }
}

#include "pch.h"

using namespace Windows::Foundation::Collections;
using namespace Platform;
using namespace concurrency;
using namespace winsdkfb;
using namespace winsdkfb::Graph;

namespace SampleCode
{
    void Initialization()
    {
        FBSession^ sess = FBSession::ActiveSession;
        sess->FBAppId = "<Facebook App ID>";
        sess->WinAppId = "<Windows or Windows Phone Store ID depending on the target device";
    }
}

Note: During development, you can always use the PhoneProductID from the manifest to get the WinAppId instead of having one Windows Store ID and one Windows Phone Store ID.For a published app you would need the package SID.

Use the following code snippet to login to Facebook. The sess.LoginAsync() or sess->LoginAsync() call launches the Facebook login dialog box for the user to enter his/her username and password.

using System;
using System.Collections.Generic;
using winsdkfb;

namespace SampleCode
{
    public static partial class SampleFunc
    {
        static async void Login()
        {
            // Get active session
            FBSession sess = FBSession.ActiveSession;

            // Add permissions required by the app
            List<String> permissionList = new List<String>();
            permissionList.Add("public_profile");
            permissionList.Add("user_friends");
            permissionList.Add("user_likes");
            permissionList.Add("user_groups");
            permissionList.Add("user_location");
            permissionList.Add("user_photos");
            permissionList.Add("publish_actions");
            FBPermissions permissions = new FBPermissions(permissionList);

            // Login to Facebook
            FBResult result = await sess.LoginAsync(permissions);

            if (result.Succeeded)
            {
                //Login successful
            }
            else
            {
                //Login failed
            }
        }
    }
}

#include "pch.h"

using namespace Windows::Foundation::Collections;
using namespace Platform;
using namespace Platform::Collections;
using namespace concurrency;
using namespace winsdkfb;
using namespace winsdkfb::Graph;

namespace SampleCode
{
    void Login()
    {
        // Get active session
        FBSession^ sess = FBSession::ActiveSession;

        // Add permissions required by the app
        Vector<String^>^ permissionList = ref new Vector<String^>();
        permissionList->Append(L"public_profile");
        permissionList->Append(L"user_friends");
        permissionList->Append(L"user_likes");
        permissionList->Append(L"user_groups");
        permissionList->Append(L"user_location");
        permissionList->Append(L"user_photos");
        permissionList->Append(L"publish_actions");
        FBPermissions^ permissions = ref new FBPermissions(permissionList->GetView());

        // Login to Facebook
        create_task(sess->LoginAsync(permissions)).then([=](FBResult^ result)
        {
            if (result->Succeeded)
            {
                // Login succeeded
            }
            else
            {
                // Login failed
            }
        });
    }
}

Logout

This is simply just calling the LogoutAsync() method.

using System;
using winsdkfb;

namespace SampleCode
{
    public static partial class SampleFunc
    {
        static async void Logout()
        {
            FBSession sess = FBSession.ActiveSession;
            await sess.LogoutAsync();
        }
    }
}

#include "pch.h"

using namespace Windows::Foundation::Collections;
using namespace Platform;
using namespace concurrency;
using namespace winsdkfb;
using namespace winsdkfb::Graph;

namespace SampleCode
{
    void Logout()
    {
        FBSession^ sess = FBSession::ActiveSession;
        sess->LogoutAsync();
    }
}

Profile Picture Control

The SDK provides a ProfilePictureControl that can be populated with the logged in user’s profile picture.

XAML:

<Page
    x:Class="SampleCode.ProfilePictureControlSample"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:winsdkfb="using:winsdkfb"
    mc:Ignorable="d">

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <winsdkfb:ProfilePictureControl x:Name="ProfilePic" Width="120" Height="120" />
    </Grid>
</Page>

using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices.WindowsRuntime;
using Windows.Foundation;
using Windows.Foundation.Collections;
using Windows.UI.Xaml;

namespace SampleCode
{
    public sealed partial class ProfilePictureControlSample : Page
    {
        public ProfilePictureControlSample()
        {
            this.InitializeComponent();
            // Get active session
            FBSession sess = FBSession.ActiveSession;
            if(sess.LoggedIn)
            {
                // Get current user
                FBUser user = sess.User;
                // Set profile pic
                ProfilePic.UserId = user.Id;
            }
        }
    }
}

#include "pch.h"
#include "ProfilePictureControlSample.xaml.h"

using namespace SampleCode;
using namespace Windows::Foundation::Collections;
using namespace Platform;
using namespace concurrency;
using namespace winsdkfb;
using namespace winsdkfb::Graph;

ProfilePictureControlSample::ProfilePictureControlSample()
{
	InitializeComponent();
    // Get active session
    FBSession^ sess = FBSession::ActiveSession;
    if (sess->LoggedIn)
    {
        // Get current user
        FBUser^ user = sess->User;
        // Set profile pic
        ProfilePic->UserId = user->Id;
    }
}

User Information

Some basic information about the logged in user can directly be accessed through FBSession.ActiveSession.User.

using winsdkfb;
using winsdkfb.Graph;

namespace SampleCode
{
    public static partial class SampleFunc
    {
        static void UserInformation()
        {
            // Get active session
            FBSession sess = FBSession.ActiveSession;
            if (sess.LoggedIn)
            {
                // Get current user
                FBUser user = sess.User;
                string userId = user.Id;
                string username = user.Name;
                string locale = user.Locale;
            }
        }
    }
}

#include "pch.h"

using namespace Windows::Foundation::Collections;
using namespace Platform;
using namespace concurrency;
using namespace winsdkfb;
using namespace winsdkfb::Graph;

namespace SampleCode
{
    void UserInformation()
    {
        // Get active session
        FBSession^ sess = FBSession::ActiveSession;
        if (sess->LoggedIn)
        {
            FBUser^ user = sess->User;
            if (user)
            {
                String^ userId = L"Id : " + user->Id;
                String^ username = L"Name : " + user->Name;
                String^ locale = L"Locale : " + user->Locale;
            }
        }
    }
}
