API
Microsoft Win32
(C / C++)
MFC
(C++)
.NET Framework
(C# and
Microsoft Visual
Basic® .NET)
Strengths
Smallest and fastest .exe files and DLLs
Lowest memory overhead
Required for device drivers, control panel applets, shell extensions
No runtime required; Windows CE 5.0 is the runtime
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
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
Framework - Weaknesses
API
Weaknesses
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
.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
