Objective-C is an object oriented language

Follows ANSI C style coding with methods from Smalltalk

Flexible because almost everything is done at runtime:•Dynamic Binding•Dynamic Typing•Dynamic Linking

Has protocols, which work like interfaces in Java they specify a number of methods a class must implement

Objective C


C++ vs. Objective-CC++ Objective C

Adds OOP, metaprogramming and generic programming to C

Only adds OOP to C

Comes with a std library Has no standard library; is dependant on other libraries

Has numerous uses Mostly used for application building

Large and complex code for OOP Simpler way of handling classes and objects

Two WP dev frameworks


framework for creating Rich Internet Application style UI

with emphasis on multimedia, animations, graphics, with features and purposes similar to those of Adobe Flash

Hardware accelerated by DX

Started on mobile with WP7 and Symbian (series 60)

• FOR:

XAML based, event driven application framework

rapid creation of a Rich Internet Application-style user interface

use Windows Phone controls

embed video inside your application

use an HTML web browser control

Silverlight and XNA Framework is focused on enabling

game developers to be successful developing on Microsoft gaming platforms

provides a complete set of managed APIs for game development

platforms WP, Xbox 360, Zune HD, Windows OS

FOR:

high performance game

rapid creation of multi-screen 2D and 3D games

manage art assets such as models, meshes, sprites, textures, effects, terrains, or animations in the XNA Content Pipeline


Developing

.NET XNA 4.0, Silverlight Microsoft Visual Studio 2010


Developing Microsoft Expression Blend, UI desing tool (vector-

based 2D widgets, and 3D widgets with hardware acceleration via DirectX), XAML-based
