Use fiddler to check where the error. Download Fiddler, install it and open it. Then run ur application. Now check the line marked with red in ur fiddler. Click that line and checks where the error comes from..

If this post answers ur question, then don't forget to mark the post as answered..

I am also getting the following error when i try to consume the WCF service in Silverlight application using VS 2010. 

"An error occurred while trying to make a request to URI 'http://localhost:3581/Service1.svc'. 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. Please see the inner exception for more details."

 I have copied the clientaccesspolicy.xml and crossdomain under $:\Inetpub\wwwroot folder but no luck. I am able to consume the same service using a windows appl as a client to make sure my service working properly.

Please could anyone help me to resolve this issue.

Thanks in advance,

Kishore

Seems like your SL application is looking for the service in the address 'http://localhost:3581/Service1.svc', if you have deployed it on IIS you should update the Service Reference.

Hi David,

I have updated the service reference and still getting the same error. Any other suggestions?

I am able to browse "http://localhost:3581/Service1.svc. On click of a button, i am calling a web method using the proxy that is where i am getting the error.

Do you change reference to service from http://localhost:3581/Service1.svc to IIS url?

Hi,

How do i host the service in IIS?. i have followed the traditional wayto host in IIS but, didn't work. Currently, self hosting the service.

Could you please send me the detail steps (hosting in IIS) to resolve this? I am new to WCF services. I am currently working with VS 2010 and the client is a silverlight application. I have selected the check box "Host the silverlight application in a new or existing web site in the solution" when i created the silverlight 3 application to consume the WCF services.

Currently, i have copied both the xml files to C:\Inetpub\wwwroot folder. Is that correct?

 Please let me know if you need more details.
