Problem with Windows RT - port

I am trying to parse a QR Code using the latest version, but this line 


var data = System.Runtime.InteropServices.WindowsRuntime.WindowsRuntimeBufferExtensions.ToArray(writeableBitmap.PixelBuffer, 0, (int)writeableBitmap.PixelBuffer.Length);


In BitmapLuminanceSource.Silverlight.cs line 50 keeps crashing with the error "Value cannot be null." 

The writeableBitmap is not null, so I do not know what is null

Can anybody help me?

I think Damir Arh gives the right answer to your question at Stackoverflow:

If not I need a sample project because I can't give you an answer based upon a single line of code.
Btw. ArgumentNullException is sometimes misleading in case of the WriteableBitmap class.
