Needed to update the ClientAccessPolicy and the CrossDomainPolicy

<?xml version="1.0" encoding="utf-8"?>

<access-policy>

<cross-domain-access>

<allow-from http-request-headers="*">

</allow-from>

<grant-to>

</grant-to>

</policy> </cross-domain-access>

</access-policy>

<?xml version="1.0"?>

<!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>

I updated the CrossDomain.xml to:

<?xml version="1.0"?>

<!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>

And removed the clientaccesspolicy.xml and I'm still getting the same exception.

I'm using a standard WCF client:

private AnalysisConfigurationService.AnalysisConfigurationServiceClient _aisc;

public void LoadAnalysisConfiguration(long analysisConfigurationId)

{

_aisc = new AnalysisConfigurationService.AnalysisConfigurationServiceClient();_aisc.AnalysisConfigurationLoadCompleted += new EventHandler<Silverlight.AnalysisViewer.AnalysisConfigurationService.AnalysisConfigurationLoadCompletedEventArgs>(AnalysisConfigurationLoadCompleted);

_aisc.AnalysisConfigurationLoadAsync(analysisConfigurationId);

}

How do you allow the use of headers in the cross domain policy in Beta 2?

There are two things you will need to check.

You MUST change your xml file to include the use of headers. You can copy the one given in the breaking changes directly.
If you are calling the service using WebRequest(not a service reference), you can't access FrameWork Elements in the callback.

I had a Silverlight 2 Beta 1 control that was calling a WCF service. Now after upgrading to Beta 2, there is an error being thrown on the AsyncCallback. The crossdomain.xml and clientaccesspolicy.xml haven't been changed.

Here is the error:
