Silverlight

Microsoft Silverlight comes with full Visual Basic language support including recently added features such as LINQ, XML Literals, and XML Axis properties. However, some run-time features of Visual Basic are not supported in Microsoft Silverlight. Features that are not supported include the My Namespace, financial functions, and file system functions.
