Hello,
I need to know if this is for Windows Phone devices or Windows Mobile devices, as both programming and user interface method would be different. For Windows Phone we will use XAML based user interface, and for Windows Mobile we could simply use Windows Forms as well. So which one you prefer? Or you need it both?
I have my own Nokia Lumia for Windows Phone apps development purpose. And I also have Intermec CN3 which is Windows Mobile 6.0 based device.
So, let me know in order I could estimate the required time-frame for the development.
