1. Microsoft
Silverlight

2. Agenda
• What is Silverlight ?
• Features
• What’s new in C# 3.0
• Controls and Containers
• Third Party Tools
• Hello World

3. What is Silverlight?
• Browser Plugin
• Earlier known as WPF/E (Windows Presentation Foundation /
Everywhere)
• Cross-browser, cross-platform, cross-device implementation
of the .NET Framework.
• < 10 sec download
• Provides animations, vector graphics, audio-video playback

4. Cross Browser
• Works on all major browsers

5. Cross Platform
• Works on Windows, Linux and Mac OS X

6. Cross Device
• Coming to Nokia and Windows Mobile phones

7. How to Install ?
1. Install Visual Studio 2008.
2. Install Visual Studio Service Pack 1.
3. Install Silverlight Tools for Visual Studio.
(Optional) Install Expression Blend for designing
XAML.

8. Supported Languages
• Silverlight 1.0
–Javascript
• Silverlight 2.0
–C#
–VB.NET
–Dynamic Lanaguages Supported
• Microsoft JScript
• IronPython
• IronRuby

9. Advantages
• Single, consistent runtime for browser-based applications.
• Performance is promising. (Prime Number Calculator)
• There is an official open source implementation of Silverlight
(Moonlight)
• Search engines can potentially index text within a Silverlight application,
just as they can with Flash.
• Silverlight interprets XAML directly (Flex doesn’t)

10. Disadvantages
• The design tools (Expression Blend and Expression Design) are
comparatively new.
• Silverlight supports SOAP web services, or REST but doesn’t have an
optimized binary protocol like Adobe’s ActionScript Message Format
(AMF), which likely means slower performance in some scenarios.
• Silverlight is a browser-only solution (Adobe has AIR).
• Development on Windows platform only.
• Yet to penetrate market.

11. Architecture

12. New Features in C# 3.0

13. New Features in C# 3.0
• Implicit Type Variables
var i = 1;
When the compiler sees this in the code, it tries to
figure out the type of the variable based on the value
you assigned it.
• Object Initializer
Human h = new Human {Name = “Fahim”, Age = 23};

14. Lambda Expressions
• A lambda expression is an anonymous function that
can contain expressions and statements.
• Example
x => x > 3
An Anonymous function that takes x (int) as an input
and returns whether x is greater than 3 or not ( true
or false).

15. Lambda Expression (Cont)
• Func<int,bool> myFunction = x => x > 3;
Console.WriteLine (myFunction ( 4 ) );
True
• Func<int,int,bool> myFunction = ( x ,y ) => x < y;
Console.WriteLine( myFunction ( 4 , 3 ) );
False

16. Attached Property
• An attached property is intended to be used
as a type of global property that is settable on
any object.
• Example
<DockPanel>
<CheckBox DockPanel.Dock="Top">Hello</CheckBox>
</DockPanel>

17. Extension Methods
• Special Kind of Static Methods
• Enable you to add methods to instances of
existing types without creating a new derived
type, recompiling, or modifying the original
type.

18. Extension Methods
class Program
{
static void Main(string[] args)
{
string name = "folio3";
Console.WriteLine(name.Decorate());
}
}
public static class StringExtension
{
public static string Decorate(this string str)
{
return "**** " + str + " ****";
}
}

19. LINQ
LINQ is a series of language extensions that supports data
querying in a type-safe way

20. LINQ
Language INtegrated Query
• The most common extension methods are the
LINQ standard query operators.

21. • Results from a LINQ query are as IEnumerable<T>
• Evaluation does not occur until you iterate the
results.
• Some extension methods (e.g Count) iterate the
results.
• Delayed evaluation means latest is always evaluated.
Re-evaluated if iterated again.
• Use ToArray or ToList to get a “snapshot”
Delayed Evaluation

22. XAML
• XAML or eXtensible Application Markup
Language is a general purpose declarative
language to create the tree of .net objects.
• Like XHTML and MXML.

23. XAML Example
<Grid>
<Button x:Name="buttonClick" Click="buttonClick_Click" Content="Click Here"
Width="100" Height="100" />
<Label Content="Click the button" />
</Grid>

24. Layout Manager Controls
• Canvas
• StackPanel
• Grid
• Border

25. Richer User Interfaces
• Calendar
• TextBox (w/
Watermark)
• Sliders
• Buttons
• Lists
• Lots more!

26. XAP File
• Really a zip file in disguise
• Contains any content marked to be included in
download and built in assemblies.
• .XAP file is what is downloaded to client machine

27. App.Xaml
• Contains Application Resources
• Entry point for the application
• This where you set your start page for the
application
• Handles following events
–Application Startup
–Application Exit
–Application Unhandled Exception

28. Job Trends
