"MFC can't be used for for Windows Store apps because it uses too many APIs that are banned for store usage. In order to allow MFC usage in your scenario we would probably have to break MFC into multiple DLLs, which would be a prohibitive amount of work."

Thanks for the link, really appreciate it. Pat Brenner has since left Microsoft so we can only wonder who is in charge of the MFC stuff nowadays.
