About me

More than 8 yrs. Of experience in Enterprise application developmentI have executed several projects for Motorola, Seagate, Cognizant , Barclays Europe & Pacific Golf, Japan.Handled clients & worked in several geographies like

London (UK)Tokyo (Japan)Malaysia

Joined TrivialWorks Solutions as Managing Partner and Director - Onshore communications.Customized & architected .NET frameworks like .NET 2.0/3.0/3.5/4.0, WCF, WPF & Cloud based applications.

.NET ?

.Net is a framework for developing web-based, windows-based, Service based & now Cloud based applications within the Microsoft environment.

The framework offers a fundamental shift in Microsoft strategy: it moves application development from client-centric to server-centric.

Intermediate Language (IL).NET languages are not compiled to machine code. They are compiled to an Intermediate Language (IL).

CLR accepts the IL code and recompiles it to machine code. The recompilation is just-in-time (JIT) meaning it is done as soon as a function or subroutine is called.

The JIT code stays in memory for subsequent calls. In cases where there is not enough memory it is discarded thus making JIT process interpretive.

.NET At The Core

16

Windows Presentation Foundation (WPF)

17

What’s Windows Presentation Foundation?

•Visually stunning user interfaces•Themes

• Unified programming model• Declarative programming• Integrated designer tools

What is Windows Presentation Foundation?What can it do for you?

19

What’s Windows Presentation Foundation?

Next generation presentation subsystem for Windows

Unified programming modelHarness the power of new graphics hardwareProvide designers direct input into project development

Enables developers and designers to create visually stunning user interfaces

20

Unified WPF API

WPF: Programming Model Unification

21

WPF: Using the Hardware

Vector-based composition engine uses the PC’s graphics power

Quality is preserved with scaleCPU freed from graphics workGain capability from graphics card advances

22

2D Graphics, 3D Graphics, Imaging

3D Graphics

23

<Border Width="400" BorderBrush="Green" BorderThickness="9"> <StackPanel> <MediaElement Source="aero.wmv" /> <Button>Hello</Button> </StackPanel></Border>

Audio & Video

Formats: WMV, MPEG, Some AVIsCan be synchronized with animationsWindows Media Foundation used to instantiate playback machinery into a DirectShow graph

24

ClearType & Antialiasing

Sub-pixel positioning & natural widths

25

Designer-Developer Productivity

• Microsoft Tools for Designers & Developers

• Declarative Programming through XAML

• Third Party Tools (e.g. Aurora by Mobiform, ZAM 3D by Electric Rain)

Designers design

With XAML designers & developers can streamline

their collaboration

Developers add business logic

26

Write Once…. & use everywhere !

WPF enables you to write the code in XAML and you are free to host it into

27

No worries for Designer tools…

This is fine…. Now lets try another….

WCF (Windows communication Foundation)

The Challenge Radically Simplifying Distributed Application Development

Development of connected systemsremains costly and frustrating

Different programming models for different tasks

Need for security and reliable messaging

Interoperability with applications on other platforms

Productive service-oriented programming model needed

31

Windows Communication Foundation

rapidly building

service-oriented applications

What’s very new…?

39

An Introduction to

Cloud Computing

40

The challenge

Add new services for your users quickly and cost effectively

41

Expand your Infrastructure!Buy new servers, increase your software costs, provision more

datacenter capacity!!

42

Look to the cloud!Pay for the bandwidth and

server resources that you need. When your push is done then

turn the whole thing off!
