@Charles: Yes, valid points; the "Win 8 style" applications have a lot of services and publishing what they can do etc..., is nice for security and so forth, but I want to make one of these from scratch from LINQPad ... yeah, it's an artificial restriction but it has a purpose to me (which I'm not ready to disclose because it might not work).  Part of the point is to try to understand how it's all put together, but it's secondary to the overall objective.
