* Readers Beware: massive code dump, not for the faint of heart… *
Hello,
I’m trying to figure out how to deploy a Silverlight 3 app to IIS7 with a WCF Service. I think i’ve got most of it figured out however I still get a cross domain error for some reason. I’m leaning toward thinking that the service is not finding the client access policy but I’m not sure how to confirm this. I get a very useless exception (simply says CrossDomainError). Inner Exception is nonexistant. Here are the steps I’ve taken to deploy the app. If anyone sees anything that doesn’t add up can they please advise? I can’t think of anything else to poke at right now…
- In IIS manager I built a new site. I named it Silverlight, accepted a pool of the same name, and accepted all the rest of the defaults. I disabled the default site. I set the web root to be C:\WebApps
- I placed all of the files from the release build of my Visual Studio Silverlight client project into the web root.
- I place the following config files from the Silverlight client project in the web root: ServiceReferences.ClientConfig, Silverlight.js.
- I placed the /bin directory from the release build of the Silverlight.Web project into the web root
- I place the following files from the Silverlight.Web release build in the web root: crossdomain.xml, clientaccesspolicy.xml, Service1.svc, Service1.svc.cs, Web.config.
- I renamed the TestPage.html file to index.html.
I realize that many of these are superfluous but I was running out of things to try so I started adding anything that looked like it might contain any useful metadata.
Here is the code to my various config files:
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 include-subpaths="true" path="/"/>
</grant-to>
</policy>
</cross-domain-access>
</access-policy>
crossdomain.xml:
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

Now for the implementation followed by the client code:

{
[OperationContract]
public DoWorkResult DoWork()
{
// Add your operation implementation here
int i = new Random().Next();
string s = "test string";
DoWorkResult r = new DoWorkResult() { String = s, Integer = i };
return r;
}
// Add more operations here and mark them with [OperationContract]
}
[DataContract]
public class DoWorkResult
{
[DataMember]
public string String { get; set; }
[DataMember]
public int Integer { get; set; }
}
}
MainPage.xaml.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;

using System.Windows.Media.Animation;
using System.Windows.Shapes;
namespace SilverlightApplication2
{
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
ServiceReference1.Service1Client proxy = new SilverlightApplication2.ServiceReference1.Service1Client();
proxy.DoWorkCompleted += new EventHandler<SilverlightApplication2.ServiceReference1.DoWorkCompletedEventArgs>(proxy_DoWorkCompleted);
proxy.OpenAsync();
proxy.DoWorkAsync();
proxy.CloseAsync();
}
void proxy_DoWorkCompleted(object sender, SilverlightApplication2.ServiceReference1.DoWorkCompletedEventArgs e)
{
if (e.Error == null)
{
String.Text = "Test String is: " + e.Result.String;
Integer.Text = "Random Int is: " + e.Result.Integer;
}
else
{
String.Text = e.Error.Message + e.Error.InnerException.Message + e.Error.StackTrace;
Integer.Text = e.Error.Message + e.Error.InnerException.Message + e.Error.StackTrace;
}
}
}
}
All of this works fine in VS 2008 on XP Pro. On IIS7 on Server2008 I am able to hit the default page, index.html, at http://localhost or at http://[myComputerName].
I am also able to hit the service at http://localhost/Service1.svc. I am not able to hit the service using http://[compNameHere]/Service1.svc. It complains with this error:

Further, I am able to hit the policy file at http://localhost/clientaccesspolicy.xml and http://[computerNameHere]/clientaccesspolicy.xml.
Is there something else I need to look at?
I had to make the following change to the ServiceReferences.ClientConfig file and then publish again:
