I am building a Silverlight front-end for an application that was initially coded for WPF using some of the design guidelines from Microsoft Patterns & Practices' Prism (Composite Application Guidance for WPF and Silverlight). We made heavy use of XamDataPresenter in WPF flavor and I am trying to reuse as much code as possible in Silverlight. Could you please help me understand what my options are when it comes to porting this code to silverlight. Is there a silverlight equivalent of XamDataPresenter or what approach should I take to share as much code between the two front-ends as I possibly can - even if that means I have to refactor or recode some parts of WPF version (but not a complete overhaul).
