Yes. I read that too. Since I do not know anything about Silverlight, I cannot use your configuration to try and find what's wrong. I guess MS tech support is the last resort if nothing goes right.
I managed to retrieve the inner exception, and posted it as a reply to Pete's last comment.

Well, I fingered out how to get the inner exception (and wrote a tip/trick about it :) ), and for your reading pleasure, here it is:
An exception occurred during the operation, making the result invalid. Check InnerException for exception details. at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary() at FMDashboard2.FMDashSvc3Ref.GetMetricDataCompletedEventArgs.get_Result() at FMDashboard2.Objects.DataRetrieval.service_GetMetricDataCompleted(Object sender, GetMetricDataCompletedEventArgs e) ============ Inner exception: An error occurred while trying to make a request to URI 'https://myUrl/FMDash3.svc/secure'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute.

doesn't this accomplish the same thing: <domain uri=”*” />

"The staggering layers of obscenity in your statement make it a work of art on so many levels." - J. Jystad, 2001If this is the way your site is set up, then yes. Alternatively, you could put both the https://* and http://* in the first allow-from if you don't have to worry about the secure path. The reason you have to add the https://* is because SL requires that you explicitly opt-in to secure services.

Well, I went ahead and made that change, and it still gives me the same exception. :/

I had it there, and in the silverlight app's folder (just in case). It didn't seem to make a difference.

I saw a comment on the web that stated moving to SL4 fixes this problem. I don't have that option. I'm going to try putting the SL app on the same server as the service and seeing if that will fix it. EDIT ======== Nope. In fact in some ways, it made it worse...

I can't. It all has to stay https (DoD network).

Unfortunately no. I do know for a fact that the app/web service work fine on my dev box. However, we haven't been able to get it to work when deployed. Because we're on a DoD network, it all has to be through https.

When I call a method in a WCF web service from a silverlight app, I get this:
An exception occurred during the operation, making the result invalid. Check InnerException for exception details. at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary() at FMDashboard2.FMDashSvc3Ref.GetMetricDataCompletedEventArgs.get_Result() at FMDashboard2.Objects.DataRetrieval.service_GetMetricDataCompleted(Object sender, GetMetricDataCompletedEventArgs e)
Calling webService.OpenAsync() succeeds, but I can't call a method (which happens to be the one and only method in the service)..45 ACP - because shooting twice is just silly
