5. Programming languages and IDEs supported 5/18

6. Programming languages and IDEs supported  IDE supported  Visual studio  Blend for Visual Studio 6/18

7. App lifecycle  Not running  Running  Dormant  Tombstoned 7/18

8. Process Isolation 8/18

9. Multiprogramming CPU backgroundforeground App 9/18

10. Multitasking  Fast Application Switching  Fast Application Resume  Idle detection 10/18

11. Scheduling employed  Background agent (subset of an App)  Periodic, Resource Intensive, Dual Purpose task  Does not support all API 11/18

12. Threading supported  Each thread maintains  exception handlers  a scheduling priority  a set of structures the system uses to save the thread context until it is scheduled  Preemptive (time slice)  Provide thread pool API 12/18

13. Future view  Windows Phone 8.1 13/18

14. Future view  Windows Phone 8.1  More API availabe  User-define UI 14/18

15. Conclusion  UI – modern (live tile) UI  Programming language - C/C++/C#/Visual Basic/XAML  Kernel – same as windows 8  Multiprogramming – background / foreground  Multitasking – Fast App Switch/Resume  Scheduling – Background Agent  Thread – preemptive(time slice) 15/18

16. Feedback  開發環境統一，方便於開發者 debug 或移植  OS UI 布局較簡單， layout 設計不複雜  提供簡約風格，自成一格  許多 API 未開放給開發者，第三方程式發展受限  Multitasking 的應用對於一般使用者較不友善 16/18
