3. Part time at Arcanic and freelance consultant Mostly backend development Past few years focus has been on Windows Phone and Windows Store (Windows 8/8.1) development

4. Portable Libraries – Sharing code between platforms Intro PCL fundamentals Demo Working with PCL Crucial/notable PCLs PCL behind the scenes

5. A lot of new.NET platforms in a short time Desktop / Core.NET Silverlight Windows Phone Windows Store (Windows 8/8.1) Xbox 360 / Xbox One Android / iOS (via Mono / Xamarin)

6. Sharing code between platforms were notoriously annoying Each platform had it’s own “class libraries” No cross-platform reusability PCL introduces shared class libraries across platforms

7. Started as a Microsoft created Visual Studio (VS) extension Built into VS 2012/2013 It appears that all new releases from Microsoft is in PCLs where it makes sense

8. You choose the platforms the library should support In return you will have a limited shared code base available

9. Principle: Lowest common denominator

10. Demo Create a PCL and selecting platforms

12. Microsoft Http Client Libraries (Microsoft.Net.Http / HttpClient) Json.NET MVVM Light

13. API: Shared API entities and API consumption Platform features through indirection MVVM: Sharing view models

14. Major improvements in.NET for restful apis Shared Entities via PCL Web API HttpClient

15. Advanced concept Requires excellent code design to be valuable Demo

16. Not everything is shared in PCL: Storage, UI pop-ups etc. We can work around this using indirection Demo

17. Profiles.NET Type Forwarding C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable

18. Shared code between platforms Available in.NET 4.0+, Windows Store, Windows Phone, Silverlight and Xbox 360 (and Xbox One?)
