From the Swiss MSDN blog:

In this 108 page hands-on lab you will learn how to use Beta 2 of Visual Studio 2010 and Beta 1 of Microsoft Silverlight 4 to create a data driven line of business style rich internet application that implements many of the new features that Silverlight 4 introduces. We will base our solution on the Windows Communication Foundation (WCF) RIA Services.

The solution will be an order-management system that shows a list of orders in a data grid and details of a selected order in a details pane. The system will validate user entries and have the capabilities of printing order reports and exporting order lists to Microsoft Excel.

Download the hands-on lab manual in PDF and Word format, the database and the final sample solution.

These features are implemented in the lab:

• True multi-tier architecture.
• Entity framework and service layer definition.
• Data filtering, paging, sorting and grouping.
• Data modification and validation.
• Foreign key management.
• Projections.
• Programmatic printing from a Silverlight application.
• COM interop with Microsoft Excel and running full-trust out-of-browser.

Grz, Kris.
