I need a simple implementation of the open source Zxing barcode scanning software for as a Windows Phone app. The app will have one basic feature. When the user opens the app, it will show a logo in the corner of the scanning screen. The zxing software should be implemented to scan QRcodes and should be able to decode and execute an SMS qrcode. Which means that it decodes the qrcode then puts the contents of the qrcode in an sms message addressed to a specified number. That's it!
