Can I Access an ADO .Net Data Service from Silverlight accross domain if I have a proper crossdomain.xml file in place and do not rely on the ADO .Net Silverlight Client components?

Question

If I create an ADO .Net Data Service, can I access it from Silverlight accross domains as long as I don't use the ADO .Net Silverlight Client helpers and I have a propery crossdomain.xml file in place? (I would essentialy just get the raw xml and parse it myself)

Asked another way, is it the ADO .Net Data Services Silverlight Client components that don't allow crossdomain calls, or is it the ADO .Net Data Service itself?

I assume it's the client components but would like some confirmation.

Answer 1

After further investigation, I found it is as I suspected, the ADO .Net Data Services Silverlight Client limits the communication to calls that are from the same domain. (Not ADO .Net Data Services itself)

This apparently is going to be fixed in a future version of Silverlight.

Answer 2

I wrote about using a Server-side proxy to make the Silverlight Client library with DataServices hosted on a different domain . http://blogs.msdn.com/phaniraj/archive/2008/10/21/accessing-cross-domain-ado-net-data-services-from-the-silverlight-client-library.aspx
