Silverlight 4.0 Hosting :: Developing a Silverlight 4.0 Application Using WCF RIA Service Class Library

Microsoft Silverlight is a powerful tool for creating and delivering rich internet applications and media experiences on the Web. Its functionality is similar to Adobe Flash, integrating multimedia, graphics, animations and interactivity into a single runtime environment. Silverlight’s initial emphasis was on providing rich media experiences; enabling designers and developers to add rich degrees of interactivity, media and animation to their websites. Later versions extended its capabilities with many new features essential for business application development. As a result there has been an increase in business applications using Silverlight.

We are going to use WCF RIA Service Class Library instead of Siverlight Business Application template. Follow the below steps.

  • Open Microsoft Visual studio 2010 and go to File >> New Project
  • In the “New Project” dialog, select “Silverlight” in the “Installed Templates”

  • Provide “Name” as “BusinessLib” and “SolutionName” as “SLBusinessAppWithRiaLibSol” and click “OK” as shown below:

  • Using “Solution Explorer”, right click on “BusinessLib.Web” project, select Add >> New Item
  • In the “Add New Item” dialog, select Common Items
