Windows Phone 8的Live SDK

Question

Hay there, I'm learning the live SDK fro windows phone 8 & I'm using Live SDK 5.5. I have downloaded the SDK, installed it and referenced it in my project I also have created a key for my application and I followed the exact code in here and that's my code: XAML

    <live:SignInButton ClientId="my ID" x:Name="btnSignin" Scopes="wl.signin wl.basic" Branding="Skydrive" SessionChanged="btnSignin_SessionChanged" Margin="10,0,-10,194" Height="104" VerticalAlignment="Bottom"  />
    <TextBlock Height="102" Foreground="White" HorizontalAlignment="Left" Margin="26,128,0,0" Name="infoTextBlock" VerticalAlignment="Top" Width="419" />
</Grid>

and that's my C# code

    private async void btnSignin_SessionChanged(object sender, LiveConnectSessionChangedEventArgs e)
    {
        if (e.Status == LiveConnectSessionStatus.Connected)
        {
            client = new LiveConnectClient(e.Session);
            LiveOperationResult operationResult = await client.GetAsync("me");
            try
            {
                dynamic meResult = operationResult.Result;
                if (meResult.first_name != null &&
                    meResult.last_name != null)
                {
                    infoTextBlock.Text = "Hello " +
                        meResult.first_name + " " +
                        meResult.last_name + "!";
                }
                else
                {
                    infoTextBlock.Text = "Hello, signed-in user!";
                }
            }
            catch (LiveConnectException exception)
            {
                this.infoTextBlock.Text = "Error calling API: " +
                    exception.Message;
            }
        }
        else
        {
            infoTextBlock.Text = "Not signed in.";
        }
    }

But the application doesn't show me the login page so that I enter my user name and password for my live account it just loads and then it says " not signed in" in the text box.

As it turned out after checking comments adding wl.skydrive to Scopes property solved the issue:

<live:SignInButton ClientId="my ID" x:Name="btnSignin" Scopes="wl.signin wl.basic wl.skydrive" 
 Branding="Skydrive" SessionChanged="btnSignin_SessionChanged" Margin="10,0,-10,194"
 Height="104" VerticalAlignment="Bottom"/>
