Microsoft Silverlight Examples
Microsoft Silverlight is a web application framework developed by Microsoft that enables developers to create rich internet applications with interactive user interfaces.
It was first released in April 2007 as a competitor to Adobe Flash, and it provides a platform-independent runtime that can be used on Windows and Mac operating systems.
History of Microsoft Silverlight
Silverlight was initially developed as a plugin for web browsers to provide rich media experiences and interactive applications. It was designed to be a lightweight alternative to Adobe Flash, with a focus on delivering high-quality audio and video content.
Over the years, Silverlight has evolved to include a wide range of features and capabilities, making it suitable for building not only media-rich applications but also line of business applications, games, and more. However, in 2012, Microsoft announced that it would no longer actively develop Silverlight, and it has since been replaced by HTML5 as the preferred technology for web development.
Features of Microsoft Silverlight
1. XAML-based UI Framework
Silverlight uses XAML (Extensible Application Markup Language) as its markup language for defining the user interface. XAML allows developers to separate the design and logic of an application, making it easier to maintain and update. Here's an example of XAML code that defines a simple button:
<Button Content="Click me!" Width="100" Height="30" />
2. Multimedia Support
Silverlight provides excellent support for multimedia, including audio and video playback, streaming, and even 3D graphics. Developers can embed audio and video files directly into their applications and control playback programmatically. Here's an example of playing a video file:
MediaElement mediaElement = new MediaElement();
mediaElement.Source = new Uri("video.mp4", UriKind.Relative);
mediaElement.Play();
3. Rich Graphics and Animation
Silverlight includes a powerful graphics and animation engine that allows developers to create visually stunning applications. It supports vector graphics, bitmap images, and animations, making it suitable for building interactive user interfaces. Here's an example of animating a button's position:
<Button Content="Animate" Width="100" Height="30">
<Button.Triggers>
<EventTrigger RoutedEvent="Button.Click">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="(Canvas.Left)" To="200" Duration="0:0:1" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Button.Triggers>
</Button>
4. Data Binding
Data binding is a powerful feature in Silverlight that allows developers to bind data from a data source, such as a database or web service, to the user interface controls. This enables automatic synchronization of data between the UI and the underlying data source. Here's an example of data binding a TextBox to a property:
<TextBox Text="{Binding UserName}" />
5. Networking and Web Services
Silverlight provides extensive networking capabilities, allowing developers to communicate with web services, retrieve data from servers, and make HTTP requests. It supports various protocols such as HTTP, SOAP, and REST. Here's an example of making an HTTP request and handling the response:
WebClient client = new WebClient();
client.DownloadStringCompleted += (sender, e) =>
{
if (e.Error == null)
{
string result = e.Result;
// Handle the response
}
};
client.DownloadStringAsync(new Uri("https://api.example.com/data"));
6. Cross-Browser and Cross-Platform Compatibility
Silverlight applications can run on multiple browsers, including Internet Explorer, Mozilla Firefox, and Google Chrome. It also provides support for running on different operating systems, such as Windows and Mac. This cross-platform compatibility makes it easier for developers to reach a wider audience.
Examples of Microsoft Silverlight Applications
Netflix: Netflix initially used Silverlight to stream video content before transitioning to HTML5. Silverlight provided a smooth and high-quality streaming experience for users.
BBC Olympics Coverage: The BBC used Silverlight to deliver live streaming and on-demand coverage of the 2012 London Olympics. Silverlight enabled viewers to watch events in real-time and access additional content.
PivotViewer: Silverlight's powerful graphics capabilities were showcased in the PivotViewer application, which allowed users to explore large collections of data in a visually immersive way.
Line of Business Applications: Silverlight was widely used for building line of business applications, such as CRM systems, inventory management systems, and financial applications. Its rich UI framework and data binding capabilities made it an ideal choice for building complex business applications.

In conclusion, Microsoft Silverlight was a powerful web application framework that provided developers with the ability to create rich internet applications with interactive user interfaces. While it is no longer actively developed, it had a significant impact on the web development landscape and was used in various high-profile applications.
