cross-domain policies in silverlight out of browser

Question

I've a silverlight application, which is running fine.

I'm trying to use "Out of browser" and I encounter several problems. First, I can't get access to my services.

I receive a "Timeout exception", even on a simple return "testString" service call. I'm on localhost.

So I think there is maybe a problem with cross-domain policies.

I tried to put this

    <?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
        <allow-access-from domain="*" />
</cross-domain-policy>

in a crossdomain.xml file

I tried to put this too:

    <?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 path="/" include-subpaths="true"/>
      </grant-to>
    </policy>
  </cross-domain-access>
</access-policy>

But no way, I'm still getting a TimeOut exception, and in server side, my break point hasn't been reached.

So what could I have done wrong?

Where exactly should I put theses files?

Because I've a local IIS server, which has only one "Site", this site has an "application", and my application has a Folder which contains services, so on which level should I put this?

Thank you very much

EDIT: In fact I don't know if this is this cross-policies problem OR if it's that because when it is in Out of Browser mode, it can't use the Windows Authentication mode(NTLM)

Have you looked at the traffic using Fiddler? That will tell you if you are getting the correct cross domain policy on the client. — Andy May, Mar 25 '11 at 12:22
In fact, if I run it out of browser, I don't see ANY traffic for this app in fiddler — J4N, Mar 25 '11 at 12:36
You have Fiddler set to all traffic, right? Not just Web Browser? — Andy May, Mar 25 '11 at 12:38
There is definitely an issue if you see no traffic. I just tested and setting Fiddler to All Processes lets me see OOB traffic. — Andy May, Mar 25 '11 at 12:39
Wait. This is localhost? Are you setting your service call to http://ipv4.fiddler: ? — Andy May, Mar 25 '11 at 12:41
@Andy: Instead of using the ipv4.fiddler weirdness just use "localhost." note the . on the end, this maintains the intranet zone status of localhost yet fiddler picks up the traffic. — AnthonyWJones, Mar 25 '11 at 12:52

I finally found what was the problem!

It was a silverlight issue:

In fact I was making the WCF call in the App.xaml.cs "ApplicationLoaded" event, and once I receive the method, I was setting my RootVisual.

And it seems, that when we are in Out-of-Browser mode, you can't make a WCF call before the RootVisual has been setted.

Now I'm setting the RootVisual, and when the RootVisual is "Loaded", I'm doing my request. and it works!
