title: A Silverlight application with .net Ria services and SilverlightFX
body: <p>I am starting to write an application in Silverlight with RIA services and SilverlightFx.
   Now this application is a pretty big one has has lot of interaction between controls.</p>
  
  <p>As an estimate it will have around 60-70 user controls. Now my questions are..</p>
  
  <ol>
  <li><p>Is it good to choose .Net Ria and SilverlightFx? (My view is..It is not going to production very soon. And as it is a big one using frameworks will help unit testing and save development time once the frameworks are understood properly.)</p></li>
  <li><p>After reading through the blogs I am not really clear how SilverlightFx handles interaction between user controls. For example I have a user control (say "S") that have the search functionality...auto complete and all...Now I have another UserControl (Say "R") that displays the search results. The display result panel can be used from search user control or another user control (Say F) that gives all items of a particular category. I can not marge Search and Select Category into a single userontrol. So how to do it?
  If I create different ViewModels how they will interect with each other?</p></li>
  <li><p>Is it better to create Domain service context in each ViewModel or to use a single one across the application?</p></li>
  </ol>
