title: Adding Entities and updating RIA domain service at runtime
body: <p>I have a requirement to deliver an app built in silverlight. Once the app has been built and delivered, any new modules that the user would request should be created as separate apps/xap and the user should be able to import the new module into the application. Its like adding new apps in an iphone.</p>
  
  <p>Now prism/mef do allow this kind of capability for the front end but the problem is with the database end. I can add some logic to create new tables for the new module but how can I update the RIA services and edmx file to handle the entities for the new module.</p>
  
  <p>Is it really possible in RIA? or is there any other technology out there that supports this kind of dynamic db update?</p>
  
  <p>Thanks</p>
