Hi Carlos I was able to implement and run the sample code you posted successfuly but get the error

"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. Please see the inner exception for more details" when running that very same code in the Web Service Software Factory. Please assist

Hi, Carlos,

It only works fine for the first 5 requests, i.e. click the "refresh" button in IE. After that, "The remote server returned an error: NotFound" exception will raise for subsequent requests. Then I have to shutdown the Service. Do you have any idea? it looks like buffer overflown.

This works great for me provided the WCF service is up and running on my local box prior to launching my Silverlight application. I have a self hosted WCF Windows service and I am hitting it from a Silverlight page using the localhost cross domain access trick above. If I do not launch my WCF service until after hitting my Silverlight page but rather launch it after, my Silverlight application can never recover. Looks like the clientaccess and crossdomain negotiation for the host domain are done somewhere behind the scenes in the client factory and I can't seem to find a way to re-initiate the check for security access. What am I missing?

How can this example *ever* work inside Silverlight when ITest.Echo is a synchronous operation?

Aside from that, even using asynchronous methods I still get a the same problem as Masande, I can browse to http://localhost:8731/Design_Time_Addresses/MyService/clientaccesspolicy.xml and see that it is being generated, however my Silverlight still throws the cross-domain exception.

When is the "Test" Method run? I don't quite understand how this works.
