We just released a new live sample that shows how to render document pages in a Silverlight 4.0 application:
http://labs.textcontrol.com/live/server/silverlight/
This sample ASP.NET web application uses TX Text Control .NET Server's Page Rendering Engine to create thumbnails from MS Word compatible documents that are presented in a Silverlight 4.0 carousel application.
The diagram below shows the design and the interaction between TX Text Control and the Silverlight application. The Silverlight application requests the images from a WCF Web Service. This WCF Web Service uses TX Text Control .NET Server's Page Rendering Engine to create high resolution images that are rendered by Silverlight using a simple System.Windows.Controls.Image control.

This application is another great example that shows how flexible TX Text Control .NET Server is. Feel free to post your comments and questions.
