XAML C# MVVM – UIOffline Translation C#Camera technologies are C++ (Ocr, Tracker … ) Assembly/compiler intrinsic when necessary. A lot perf issues that had to be overcomed in order to ship camera translation on WP7Rendering is XNA for WP and Direct3D for windows (moving to Direct3D)Windows Azure for language pack downloads, and Live Tile updates.
All core technologies are shared code bases+ LZMA + part of the app logic.C++ is still the most portable code (JS doesn’t come close)OCR runs on iOS, Android… Offline transition built as a service moved to mobile platforms using C#.API’s between the platforms are coming closer (Storage, Network, Direct3D, same .NET).XAML C# MVVM can be used on both platforms but different form factors require different UX
- It’s in pipeline
