V1.0 of the WP7BarcodeLibrary.DLL assembly. You can reference this in your project if you just want a Silverlight version of the ZXing library (see com.google.zxing namespace).

If you plan on using any of the Windows Phone 7 specific code from the WP7BarcodeLibrary.WP7Code namespace you probably want to download the full source and compile it yourself so that you can edit/debug the code.

I plan on cleaning up the code and adding more documentation in the next few weeks.
