What is WPF?
WPF is a new API for building Windows applications
The goal of Windows Presentation Foundation (WPF) is to provide these advances
for Windows. Included in version 4.0 of the Microsoft .NET Framework, WPF allows
building interfaces that incorporate documents, media, two- and three-dimensional
graphics, animations, Web-like characteristics, and much more.

What Windows Presentation Foundation Provides?
Three most important:

a unified platform for modern user interfaces

the ability for developers and designers to work together,

and a common technology for Windows and Web browser user interfaces.

What is WPF good for?

To enable designers and developers to work together


To allow an easy way to customize the look of controls without changing its
behavior

To allow 3D graphics more easily in Windows applications

To allow an easy way to do animations in Windows applications

To enable the creation of applications which scale nicely to high resolution
screens

Which of these UI have you worked with?

GDI (20 years), GDI+, WinForms

DirectX (11 years), Direct3D

Quartz, DirectShow (8 years)
– Problems:
• Showing their age
• Each API is different
• Mixing APIs is challenging

Next Gen

WPF – replaces GDI

Direct3D – large games, used by WPF

Media Foundation – ultimately will replace DirectShow


MCML –markup language for Media Center Edition applications

XNA – small games

WPF

Declarative programming with XAML markup

For Designers and Developers

Rewritten from scratch
– Built on top of Direct3D
– Hardware accelerated
– Vector based
– Resolution independent (1/96 inch)
– Retained graphics


Most of WPF is written in
managed code

milcore is the only unmanaged
component of WPF
Overview of WPF Architecture
HO CHI MINH UNIVERSITY OF INDUSTRY
Managed Code:
Code write in .net framework environment is call Managed code, they will be
executed direct from CLR(Common Language Runtime). CLR will manage
memory, security problem, debugging…and other useful features

HO CHI MINH UNIVERSITY OF INDUSTRY
Unmanaged Code
Not in .net framework, that is not controlled by CLR, Unmanaged Code will
bee execute with 2 wrapper class support:
CCW (COM Callable Wrapper)
and
RCW (Runtime Callable Wrapper).

XAML:
Extensible Application Markup Language

Declarative object instantiation

Not exclusive to WPF

Separates UI and logic
– Common language for Designers and Developers
• Demo: Blend and VS
– Parallel development
– Localization, Branding
– Targeted UI (devices, users, …)

Tool support

Supports C# and VB.NET

Benefits

Markup/code-behind model (like ASP.NET)

Excellent layout options and text flow features

Access to powerful graphics hardware

Certain otherwise-impossible effects are made easy (skewing and rotating
textboxes, etc.)
