    Silverlight Error: CommunicationException Error....

    Hi Guys,

    This is my first post on this forum. I got this error when i clicked on the save button of my silverlight client application. It calls a CreateRecord Function in a service that executes asynchronously. I made use of LINQ2SQL Entities which reside in a separate project-n tier setup.

    A first chance exception of type 'System.ServiceModel.CommunicationException' occurred in System.ServiceModel.dll
    A first chance exception of type 'System.Reflection.TargetInvocationException' occurred in system.dll

    I've deleted the service reference and recreated it severally to no avail. I'll be very grateful for the solution. Thanks.

    Hi Guys
    I finally found a solution!!! I found out that all i needed was a cross-domain policy xml file. Guess what? It works for ALL silverlight projects! Its not project specific! These are the contents right here:
    Code:
    <?xml version="1.0" encoding="utf-8" ?>
    <access-policy>
      <cross-domain-access>
        <policy >
          <allow-from http-request-headers="SOAPAction">
            <domain uri="*"/>
          </allow-from>
          <grant-to>
            <resource path="/" include-subpaths="true"/>
          </grant-to>
        </policy>
      </cross-domain-access>
    </access-policy>
    There it is! THING OF BEAUTY i tell ya! Thaks All for viewing the thread and at least making an effort to give me a solution(I believe anyone who views a thread does so for one of two reasons-either to read it and learn from it if theres a reply OR to make a contribution to it if there isnt a reply!) You Guys are the best! HAve a GR8 day Folks!
