Re: Use Existing WCF service in Silverlight

Hi,

you have to verify the WCF web.config configuration file: the binding must be set to "basicHttpBinding" (your service could use instead wsHttpBinding which isn't supported by Silverlight).

You also have to put a clientaccesspolicy.xml or crossdomain.xml file like the following on the root of your domain:

clientaccesspolicy.xml

<?xml version="1.0" encoding="utf-8"?>
<access-policy>
  <cross-domain-access>
    <policy>
      <allow-from http-request-headers="*">
        <domain uri="*"/>
      </allow-from>
      <grant-to>
        <resource path="/" include-subpaths="true"/>
      </grant-to>
    </policy>
  </cross-domain-access>
</access-policy>
