Last Updated on Thursday, 9 August 2012 12:33 Written by Andrew Ivanov Friday, 31 August 2012 12:00

If you have installed Microsoft Silverlight SDK v4.0, but your Visual Studio displays the message “Could not find Microsoft Silverlight SDK v4.0. Please make sure that the correct version of the Microsoft Silverlight SDK has been installed.” and you cannot edit XAML in designer, so you have the same problem that I encountered yesterday

But that’s okay, today I will tell you how I managed to restore Silverlight:

Silverlight is a cross-browser (Internet Explorer, FireFox, Safari, etc.), cross-platform (Windows, Mac, Linux, etc) plug-in that delivers ASP.NET-based media, such as music, videos and other streaming entertainment services. Similar to flash programs like Adobe Flash Player, Silverlight allows you to view these media applications directly in your browser in a streamed setting–that means you can watch videos and listen to music in near-real time. Silverlight can also be integrated with other web applications.

Microsoft is synonymous with technology, so it is no surprise that it is always looking into new ways to push Internet technology to its limits and capitalize on the success of its products and services by offering everything under one brand. Thus, when Microsoft launched Silverlight to compete with other online flash media applications, the industry took notice. Now, Silverlight is one of the lead competitors in the online media market.

Silverlight: Avoiding Cross-Site Scripting Attacks

Cross-site scripting (XSS) describes a vulnerability typically found in Web applications. If steps are not taken to prevent this type of vulnerability, an attacker can inject code (typically JavaScript) into Web pages hosted on different domains. For more information about XSS and other kinds of client vulnerabilities, see Client-side Cross-domain Security. For Silverlight, XSS issues are possible, but less likely than in traditional HTML development. However, an exploited cross-site scripting vulnerability can give the attacker access to any cookies, isolated storage, and authentication data that the browser would normally only give to a legitimate client.

In Silverlight, XSS issues typically occur when attacker-controlled strings are inserted into markup without first validating or escaping the attacker-controlled string.

You can apply 3-D effects to any Silverlight UIElement using what are called “perspective transforms.” For example, you can create the illusion that an object is rotated toward or away from you, as shown in the following illustration.
