Summary• Cross mobile development

• Xamarin

• Technical differences

• Code sharing:• Shared Project • Portable Class Libraries

• Xamarin Forms

• Conclusion

Cross mobile development

• Single codebase for different platforms

• Reusage of data access and business layer

• Two approaches: • Web app wrapped as a native app • Native app

Xamarin• Platform

• Forms

• Test Cloud

• Insights

• Xamarin for Visual Studio

• Xamarin Studio
