Visual Studio LightSwitch: binding a Silverlight Pie Chart control to screens

In reality, LightSwitch applications are 100% .NET applications running on the Silverlight 4 platform, meaning that you can reuse a lot of your existing skills about .NET and managed languages, such as extension methods. For example, imagine you have a simple entity named Contact which exposes a property called WebSite of type String, which stores the contact's web site...
