I’m not a big fan of #region, I use it occasionally but generally try to avoid it. It’s always frustrating to open a code file and be presented with nothing but collapsed regions – sure, it looks neat (and lets face, more than a few programmers are a little OCD) but I want to see the code, that’s why I opened the file in the first place!
Don’t worry, I’m not going off on a rant, I just want to direct you to a much more level headed explanation of The Problem With Code Folding. I couldn’t agree more.
