title: C# silverlight - WCF calls
body: <p>I have a silverlight application which has some calls to a WCF service. Both silverlight and WCF are located on the localhost. when I run the silverlight application but it fails in the calls to WCF in communication exception. Iv'e understand fron the web that this can be because the WCF and silverlight are not running on the same port and I have to add clientaccesspolicy.xml file.
  but I didn't understand what is the "domain root" I have to locate there the xml.
  can you please inform me the path I have to locate the xml there (on localhost)</p>
  
  <p>thanks!</p>
