Hi Rudi,
Ryan and I put together a video where we explore Linq. There is no WebGui here, but the underlying technology here is still quite impressive. And of course, since we're using Windows Forms, transitioning to VWG should be easy.

Yes, our framework will require LLBLGen. However, we think you will really love llblgen once you use it.
As for a c# conversion of the URL Component, there are a few options of online code converters, and we have our hands full at the moment. If you have any problems, we'll try to help you step through the.
