Add a cross-domain file

File contents:

Adding a WCF service reference in a Silverlight application

Import namespaces

using Silverlightwcfclient.workerinfoservicereference;

code example:

         Public voidGetworkerinfo () {workerinfoserviceclient client=Newworkerinfoserviceclient (); Client.getworkerinfocompleted+ = client_getworkerinfocompleted;//vs version, this line of code will varyClient.getworkerinfoasync (); }        voidClient_getworkerinfocompleted (Objectsender, Getworkerinfocompletedeventargs e) {            if(E.error! =NULL)                return; if(E.result.count >0) {Dgworkerinfo.itemssource=e.result.tolist (); }        }
