I\"m trying to connect my Silverlight application to a WCF service that I\'m hosting myself. I\'ve created a clientaccesspolicy.xml file, and placed it in the service host p
The clientaccesspolicy.xml file must be in the root of the domain where the service is hosted. You may already have it there but the virtual path of the web site or web application from the property page will need to be changed to "/"
See this page for more information.
I did not understand how you're hosting your WCF service?
Is it hosted in a asp.net application or a windows host (self-hosting)? If the latter is the case, you may have to implement a clientaccesspolicy service that provides the content of the clientaccesspolicy.xml file on request.
For example like this.
