Self hosted cross domain WCF service called from silverlight hosted in sharepoint

Question

Hello,

as the title already states I am trying to call a self hosted WCF service (hosted in a windows service) from a silverlight 4.0 application which is hosted in sharepoint 2010. I use the basicHttpBinding and I already tried a lot of things as suggested here:

or here

but none of them worked I still get the error:

An error occurred while trying to make a request to URI 'serviceuri'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. Please see the inner exception for more details.

The inner exception states:

when deploying an Office solution, check to make sure you have fullfilled all security requirements.

The two files clientaccesspolicy.xml and crossdomain.xml are accessible on http://myserver/clientaccesspolicy.xml and http://myserver/crossdomain.xml

Does anybody have an idea on how to solve this?
