9. Framework - Strengths APIStrengths Microsoft Win32 (C / C++) Smallest and fastest.exe files and DLLs Smallest and fastest.exe files and DLLs Lowest memory overhead Lowest memory overhead Required for device drivers, control panel applets, shell extensions Required for device drivers, control panel applets, shell extensions No runtime required; Windows CE 5.0 is the runtime No runtime required; Windows CE 5.0 is the runtime MFC(C++) Object-oriented. Inheritance, Encapsulation, Polymorphism, also called.function overloading Container classes support arrays, lists, object maps and simplify data handling Type safety Complete MFC source code ships with Embedded Visual Tools Good tool support & wizards.NET Framework (C# and Microsoft Visual Basic®.NET) Well-designed programming interface Object-oriented. Inheritance, Encapsulation, Polymorphism, also called function overloading Container classes support arrays, lists, hashtables, dictionaries, and stacks Type safety Namespaces Automatic garbage collection eliminates memory leaks Portable machine instruction set, MSIL / CIL, provides binary portable of executable (.exe &.dll) files Web service clients are quick and easy to write Great support for handling XML Great tool support — Forms Designer

10. Framework - Weaknesses APIWeaknesses Microsoft Win32 (C / C++) Object cleanup is the responsibility of the application/driver programmer, making this API prone to memory leaks Low-level API — can be hard to learn Procedure-oriented API, not object-oriented MFC (C++) Object cleanup only semi-automatic, therefore less prone to memory leaks than Win32, but still somewhat vulnerable since MFC is thin wrapper on top of Win32 Size of runtime ~ 500 KB (MFC & OLECE).NET Framework (C# and Microsoft Visual Basic®.NET) Size of runtime ~ 1.5 MB Overhead of calls between managed and unmanaged code is high COM Interoperability somewhat clumsy. Requires writing Win32 wrappers that call the COM interface functions Source code is not available Requires display based platform

11. .NET Compact Framework Lightweight version of.NET Framework Designed for resource-constrained devices Compatible with VS.NET, C#, VB.NET Runs applications securely on-device High performance JIT compiler Guarantees robustness and security Highly interactive, offline, and networked experiences Makes it easy to consume web services Tunable size and performance
