We have used ESRI maps in our silverlight application which was developed back in 2010. Now we are again working on that application, the application basically displays the map on loading. It used to show the map in 2010, but the same application won't display the map now and throws the following error:

The map does not show at all and we see a blank white page in the area of where the map should have been shown. We tried using the new ESRI silverlight dll's in our application and also updated the silverlight dll's, We also tried resetting our IIS server, but still we get the error.
Kindly provide us a solution if you have encountered the same issues.
The SL API, like more generally the REST API, doesn't support multi-layer caches. AFAIK, this has never been supported. So my best bet to explain this new issue is a change at server side from fused cache to multi-layer cache.
