Reviews for this release

It's really a great work. Many things to learn. Although, project description states objective clearly, I have a suggestion. If accompanied by 'step by step guide' it would be great learning experience for newbies like me. At least code comments and a full problem statement will make better understanding of functionality. your efforts are uncomparable. Thank you very much.

Thanks for this job. But I have a couple of questions. 1. Why didn't you choose WWF State Machine? I have understood that State Machines workflows are used to human being interactions. 2. Why you use UI process? If you are able to do all of this in the same Windows Form class. I mean, validation and communication with other layers could be done in the same class. Thanks a lot, again!
