Microsoft started sponsoring The Times Spelling Bee in 2010 and wanted an app for Windows Mobile.
I was tasked with replicating the popular Times Spelling Bee iPhone app on Windows Mobile.
After doing research and prototyping, I decided we should support WVGA, VGA and QVGA, touch enabled, Windows Mobile 6.x devices using the .NET Compact Framework. The build was very challenging as the .NET Compact Framework was not intended to build such a rich interface. The other main challenge was that the hardware capabilities of the devices vary significantly.
