Include you ZXing.Net library into your project.

View.xaml

<Grid x:Name="grdCamera">
<Rectangle x:Name="_previewRect" 
       Margin="0" 
       Height="800" 
       Width="600" 
       HorizontalAlignment="Center" 
       VerticalAlignment="Center">
    <Rectangle.Fill>
        <VideoBrush x:Name="_previewVideo">
            <VideoBrush.RelativeTransform>
                <CompositeTransform  
                x:Name="_previewTransform" CenterX=".5" CenterY=".5" />
            </VideoBrush.RelativeTransform>
        </VideoBrush>
    </Rectangle.Fill>
</Rectangle>

C# code

private readonly DispatcherTimer _timer;
private PhotoCameraLuminanceSource _luminance;
private QRCodeReader _reader;
private PhotoCamera _photoCamera;

//Constructor
public ScanPage()
{
    InitializeComponent();

    _timer = new DispatcherTimer();
    _timer.Interval = TimeSpan.FromMilliseconds(250);
    _timer.Tick += (o, arg) => ScanPreviewBuffer();
}

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    _photoCamera = new PhotoCamera();
    _photoCamera.Initialized += OnPhotoCameraInitialized;
    _previewVideo.SetSource(_photoCamera);

    CameraButtons.ShutterKeyHalfPressed += (o, arg) => _photoCamera.Focus();

    base.OnNavigatedTo(e);
}

private void OnPhotoCameraInitialized(object sender, CameraOperationCompletedEventArgs e)
{
    int width = Convert.ToInt32(_photoCamera.PreviewResolution.Width);
    int height = Convert.ToInt32(_photoCamera.PreviewResolution.Height);

    _luminance = new PhotoCameraLuminanceSource(width, height);
    _reader = new QRCodeReader();

    Dispatcher.BeginInvoke(() =>
    {
        _previewTransform.Rotation = _photoCamera.Orientation;
        _timer.Start();
    });
}

private void ScanPreviewBuffer()
{
    try
    {
        _photoCamera.GetPreviewBufferY(_luminance.PreviewBufferY);
        var binarizer = new HybridBinarizer(_luminance);
        var binBitmap = new BinaryBitmap(binarizer);
        var result = _reader.decode(binBitmap);
        Dispatcher.BeginInvoke(() => MessageBox.Show(result.Text));
    }
    catch
    {
    }
}

finally ..I have implemented this method..

Include following namespace on your sample

xmlns:jwqr="clr-namespace:JeffWilcox.Controls;assembly=JeffWilcox.Controls.QR"

in XAml file.. include the following control

<jwqr:QRCodeScanner
ScanComplete="QRCodeScanner_ScanComplete"
Error="QRCodeScanner_Error"
Width="400"
Height="400"/>

In code behing..include the event handlers.

private void QRCodeScanner_ScanComplete(object sender, JeffWilcox.Controls.ScanCompleteEventArgs e)
{
ApplicationTitle.Text = e.Result;
}

private void QRCodeScanner_Error(object sender, JeffWilcox.Controls.ScanFailureEventArgs e)
{
throw e.Exception;
}
