I have spent a time working on a business multiplatform app which shares almost all its code between two "plaforms": Command line app (Net 4.0) and Windows Phone 7.

Last decision we took was to add Windows 8 to the list of supported platforms, and obviously the doubts arised early when I took a look to the new async I/O methods offered by WindowsRT API.  So, this post is an attempt to help others in the same situation I was to don't make same mistakes I made.
