Map not showing in Silverlight

LuisGarcia2

I installed both the WPF and Silverlight 2.4 implementations of ESRI control map. I created a quick  Wpf application project in VS 2010 just to check all works fine. I added a map to the default form and it shows both in design mode and at run time. I did the same thing for a Silverlight application and the map does not show in either run-time or design mode. I do have Silverlight SDK 4.0 installed. Am I missing something else?
Thanks!

Map not showing in Silverlight application is mostly common but always easy to resolved problem. Just follow these steps to check where the issue is:
1. Ensure your map service is running by displaying it in Arcmap or Javascript API(from services directory);
2. Ensure you have the cross domain file in your web server and in the right place;
3. Ensure using the right class to add the map service. Note the difference between ArcGISDynamicMapServiceLayer and ArcGISTiledMapServiceLayer;
4. If now the problem remains, just using Fiddler or Firebug tools to check what happened during the map image loading course.
