Is there a way to render the Zxing ScannerPage in Xaml?

I'm using the MVVM approach to make a small scanner app. I have a startPage.Xaml with one button binded to a command in the viewModel that opens my scannerPage.Xaml On the scannerPage I have just a simple footer, and want the scanner object to fill the rest of the page. However, when I add the scanner object to my stackPanel I get the following exception: "System.MissingMethodException: Default constructor not found for type ZXing.Net.Mobile.Forms.ZXingScannerPage". I'll list my xaml code below. Any help will be much appreciated. Thanks
