Datasets not supported
Solution - Use LINQ to XML that can read XML into a generic list for databinding purposes
Master Pages not supported
Solution - Create a parent XAML page, and have the rest of the application created using User Controls so you can switch between them

Solution - Use the OBJECT tag instead of the ASP.NET Silverlight Tag.
