This document discusses mobile application development strategies using Visual Studio. It outlines tools for building cross-platform mobile apps using Xamarin, Cordova, and C++. Visual Studio allows developing native iOS and Android apps using C# with Xamarin. It also supports developing hybrid apps with Cordova using HTML, CSS, and JavaScript. Visual Studio's emulators and tools help build and debug apps for Windows, iOS, Android and more from a single IDE.

9. Xamarin & Visual Studio

10. .NET and Xamarin
Share app logic across platforms
• Native apps for Windows, iOS and Android
devices using .NET
• Most productive and powerful platform for
creating native applications
• Maximize code reuse with Universal Projects &
Portable Class Libraries
100% APIs exposed
• Everything you can do in xCode or ADT you can
do with Visual Studio
C# + XIB C# + AXML C# + XAML
Native UI Native UI Native UI

11. UI design
Create UI with drag and drop simplicity
Target multiple screen sizes, resolutions,
and OS platform and versions
Layouts saved in native
resource formats
World’s best Android designer
available in Visual Studio
iOS app designer in Visual Studio
Android app designer in Visual Studio

12. Native compilation, native performance
Xamarin.iOS does full Ahead Of Time (AOT) compilation to
produce an ARM binary suitable
for Apple’s App Store
Xamarin.Android takes advantage of
Just In Time (JIT) compilation on the Android device

13. Universal Windows Apps

14. The design to each device

15. Visual C++ Cross Platform

16. Cross-platform mobile apps in C++
Easy installation
One C++ IDE for cross-platform dev
Share and reuse cross-platform code
State of the Art code-editing features
Powerful debugging experience
Fast emulation

17. C++ the common denominator
Shared C++ backend is compiled as:
DropBox

18. Development tools for C++ cross-platform

19. Visual Studio Emulator for Android
Fast, x86 image built from AOSP
Runs on Hyper-V
Comes with Visual Studio
Speaks Android Debugging
Native capabilities and sensors
Zoom, Rotation, Network, Location, Accelerometer, Battery, OpenGL
SD Card, Camera, Audio playback, Keyboard Input, Screenshots,
Version and Screen Size Configurations, Drag&Drop APKs

20. Tools for Apache Cordova
• Productivity of Visual Studio for hybrid apps
• Scale to complex Enterprise apps through optional
TypeScript support
• End-to-end development workflow included for
Windows, iOS and Android
• Flexibility to use any JavaScript framework
• Interops with common command-line tools
Hybrid HTML apps
Cordova tooling in Visual Studio
• Natural path for web developers targeting devices
Black Box

21. Visual Studio Tools for Apache Cordova™

22. Best practice
• Use technology you knows
• Cover all platforms first
• Automate everything first
