Why Silverlight?
Features of Silverlight are:
 It's FREE.
 It runs on all popular browsers, platforms, and devices.
 It can be run in browser and as a desktop application.
 Easy to create.
 Enables business application development.
 Supports 2D/3D animations/graphics.
 Natively supports CLR and .NET Framework.
 Can be automated using JavaScript.
 Supports a variety of media (audio/video) formats with
streaming capabilities.
 Supports a variety of rich controls including
the DataGrid.

 Silverlight is a Microsoft technology aimed to help developers create
rich interactive Web applications with the best user interface features
and business logic functionalities.
 It’s subset of WPF.
 It`s adobe flash competitor.
 Its provide flash functionality with business logic.
What is Silverlight?

Silverlight Best Suited for Following
 Advanced Graphics and Animations.
 Data Visualization with AJAX technology.
 Rich Interactive games, Web gadgets, and Ad Banners
 Advanced Media Applications

Silverlight is comprised of four main parts:
 Silverlight Plug-in
Silverlight Host, the Web Page.
Silverlight Application File (.XAP)
The Interface language, Extensible Application Markup Language
(XAML).

 A Silverlight Plug-in is the engine that renders the
Silverlight application in the browser.
 The host is the web page where Silverlight Application is hosted,
 The Silverlight Application is the Internet Application which is
developed using Microsoft Visual Studio and Expression Blend.
 The core of the Silverlight technology is an Extensible Application
Markup Language (XAML) which is a declarative programming language
used to create rich vector graphics and animations and is used in
theSilverlight Application file.

RICH Interactive Applicaton
 A Rich Interactive/Internet Application (RIA) is a Web application
that’s very interactive with the user and has lots of functionalities.
 It’s very similar to desktop applications comparing interactivity and
features; however, it’s a Web application that runs on the browser not
the desktop.
 So we can say that RIA applications have the best functionalities and
user interface features of desktop applications and Web applications.
 Today, there’re lots of technologies
available for creating RIA applications. The
most famous platforms are Adobe Flash,
Microsoft Silverlight, and Sun Java. It is worth
mentioning that every platform of the above
mentioned is available through a plugin for the
browser, and therefore its runtime must be
installed on user’s machine in order to be able
to run the application. .NET TRAINNING IN GANDHINAGAR

Platform Support
 Unlike many other Microsoft technologies, Silverlight applications
can run everywhere. It’s said to be cross-platform, cross-browser, and
cross-device.
 It can run on Windows, Linux, and even Mac, it can run on Internet
Explorer, Mozilla Firefox, Google Chrome, and many others, and it also
can run on PCs, mobile devices, and handhelds. Really it can run
everywhere without any code changes!
 One more interesting thing is that Silverlight Web applications can
be hosted on any server. You can host your Silverlight application on a
Windows, Linux, or Mac server without any additional code changes or
configuration.

Advantage of Silverlight:
 Vector based vs. pixel based
 Scalable – Looks good at multiple resolutions
 XAML – Similar to HTML
 Declarative
 Designers and programmers work in parallel
 Rich customization is possible in a well-designed way
Silverlight you get cross platform.

Limitation of Silverlight:
 Limited image support. Like silverlight fully supported “.jpg” ,
“.png” extension but limited suport “.gif” extension.

Silverlight VS WPF
 Windows Presentation Foundation (WPF) is a graphical
subsystem utilizing DirectX for rendering UI in Windows-based
application, developed by Microsoft and introduced as part of
Microsoft .NET Framework 3.0 and Windows Vista.
 Silverlight is actually a subset of WPF,
and formerly Silverlight was codenamed
WPF/E (WPF/Everywhere) because it’s
considered to be the cross-platform version
of WPF.
 WPF focuses on desktop development,
Silverlight focuses on Web development.

Silverlight Deep Zoom
 feature of Silverlight is the DeepZoom technology that was
introduced by Microsoft as part of Silverlight.
 DeepZoom allows you to view very large high resolution
images.
 It reduces the time of initial load by downloading only the
region being viewed at the resolution it’s displayed at.
 Subsequent regions are downloaded as the user pans to (or
zooms into) them.

Silverlight and XAML
 Like WPF, user interface in Silverlight is declared in a specific
language called Extensible Markup Language (or XAML,
pronounced ‘Zammel’.)
 XAML is an XML-based language created by Microsoft which is
used to initialize structured values and objects.
 XAML elements are mapped directly to CLR objects.

 Asp.net Developer and and Designer To create an application
there are two files are create.
 The concept of two files for the same page (e.g. a XAML file for
the interface and a CS file for the C# code) separates two main
roles in application development, design and development.
 The designer can work in the XAML file, and the developer can
work in the code file, and both files are linked together.

Deployment Process:
 When you build your Silverlight application, the XAML markup, as
well as the code and all other resources, is compiled into .NET
assemblies which are then compressed using ZIP and stored in a XAP
(.xap) file.

 The XAP file can then be hosted in a Web server and
referenced by Web pages declaring the Silverlight plugin object.
And when the user navigates to the page, the XAP file is
downloaded to his PC and executed on the Web page by
the Silverlight runtime.
 So all you need is just to develop your application, get the
XAP file, insert the plugin into a Web page, and then publish
the page and the XAP file to the Web.
.

Silverlight Processing Model
 Silverlight works much like Javascript
 Gets loaded with the page (html or aspx).
 Events, like the button click in the previous slides, are processed
by bindings between a silverlight control (the button) and an
event handler, button1_click.
 This works just like Javascript events, with no postback to the
server.

Interactions with Asp.Net
 Basically none!
 Silverlight code-behind can call JavaScript functions provided by
the aspx page using Html Document and Html Page classes from
the System.Web.Browser namespace.
 Silverlight code-behind can use a server-based web service .
 So Silverlight can be:
 A decoration on a page
 A control that draws

Using the Toolbox
 You will find that when you pull controls from theToolbox:
 They do not drop onto the designer surface
 They do drop onto the Xaml display if it is in focus
 You will probably add controls most often simply by writing the
Xaml.
 Intelligence is a big help for that.

Demo – For Animation
.

Summary
 Silverlight is a useful subset ofWPF
 Silverlight complements Asp.Net
 Can be served on Asp.Net pages
 Can not directly communicate with Asp.Net code.
 Runs on browser in scaled-down CLR.
 Can communicate with JavaScript
