Tim,
I sometimes use several files to split
>In my opinion the #region is goog organization of code and I use much the same as Viv. Using ReSharper helps navigate code but sometimes for instance if I have many properties in a class, collapsing the region around the properties makes the file more manageable to wonder through. I don't view it as hiding code, but rather just part of organizing.
