Windows Mobile Roadmap Richer Platform Capabilities.NET CF “Whidbey” MFC 8.0, ATL 8.0 Broad managed code support Notification broker, Location, Camera, SQL CE, D3DM.NET CF SP2 VGA (PPC) Square (PPC) Landscape (PPC) QVGA (SP).NET CF Enhanced Emulator Configuration Mgr, Bluetooth, SMS MFC 3.0, ATL 3.0 Active Sync Connection Mgr MAPI OBEX Telephony MFC 3.0 Win32, POOM MFC 3.0 Win32, POOM Better Development Visual Studio 2005 formerly VS “Whidbey” (C#, VB.NET, C++) eVC 3 (C++) eVC 4 (C++) VS.NET 2003 (C#, VB.NET) eVC 3 (C++) eVC 4 (C++) VS.NET 2003 (C#, VB.NET) eVC 3 (C++) eVB 3 (VB) Core OS WinCE “Macallan” WinCE 4.2 WinCE 3.0 WinCE 3.0 WinCE 3.0 More Device Choices Future Windows Mobile 2003 Second Edition 200320022000

5. Why Use Native Code Managed Code limitations (CF 1.0) Managed Code limitations (CF 1.0)  System Extensions  No CLR hosting  Home screen add-in’s, Drivers, other dll’s  COM interop  Wrapper classes  Complex interfaces i.e. MSMQ, Registry  Performance  GAPI, complex math, specialized optimization Migration / legacy / porting Migration / legacy / porting

8. Development Choices APIStrengths Microsoft Win32 (C / C++)  Smallest and fastest.exe files and DLLs.  Lowest memory overhead.  Required for device drivers, control panel applets, shell extensions  No runtime required; Windows CE.NET is the runtime. MFC / ATL (C++)  Object-oriented. Inheritance, Encapsulation, Polymorphism  Classes support arrays, lists, and simplify data handling.  Type safety  Complete MFC/ATL source code ships with tools.  Good tool support & wizards.NET Framework (C# and Microsoft Visual Basic®.NET)  Well-designed programming interface.  Object-oriented. Inheritance, Encapsulation, Polymorphism  Classes support arrays, lists, hashtables, dictionaries, and stacks.  Type safety  Namespaces.  Automatic garbage collection eliminates memory leaks.  MSIL / CIL, provides binary portable of executable (.exe &.dll)  Web service clients are quick and easy to write.  Great support for handling XML.  Great tool support — Forms Designer

9. Developing with Embedded Visual C++ 4.0

10. What do you need? EVC 4.0 with Service Pack 2 or 3 EVC 4.0 with Service Pack 2 or 3  Side by side with v3.0, VS.NET 2003 Requires SDK’s for Device Dev Requires SDK’s for Device Dev  Windows Mobile 2003 SDK provides headers, lib’s, help etc. Active Synch 3.6 for Device Debugging Active Synch 3.6 for Device Debugging  Not required, but very useful  Prefer using Ethernet connection.
