In what originally struck me as odd Chunsheng Tang of Microsoft posted questions in the MSDN Smart Device forums and then posted the answers to his own questions. He is one of the modorators for the MSDN forums and usually answers questions, but never asks questions. When I took a closer look at the threads it made sense. The questions he was posting are questions that are commonly asked by developers and he was posting reference material for when those questions come up in the future.
It's always nice to have a reference that can be brought up when users post some of these common questions. If you are active in the forums I encourage you to bookmark these threads so that you have quick access to them when users ask these questions.
