I just got home after my session at the Windows 8 App Day in Antwerp, Belgium, in which I went into detail on how we built MINE for Facebook (a Facebook client for Windows 8, which was released to the Windows Store yesterday, in preview version).
I talked about… well… essentially, I just talked A LOT :-) On the UX-side, some of the topics included the importance of consistency, UX & visual design. Some of the more dev-oriented topics included app architecture, achieving reliability, improving performance (task cancellation, producer/consumer pattern) & gathering statistics.
If you’re interested in those, feel free to download the slidedeck.
Happy coding :-)
