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.
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.
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).
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
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.
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
