Silverlight cross-origin access to the WCF Service

When using Silverlight to call WCF in other domains, the following error occurs:

....

This may be because there is no correct cross-origin policy when attempting to access the service in the Cross-origin mode, or the policy is not applicable to the soap service. You may need to contact the service owner to publish a cross-domain policy file and ensure that the file allows sending HTTP headers related to soap. This error may also occur because the internal type in the Web Service proxy is used, but the internalsvisibletoattribute attribute is not used. For more information, see internal exceptions...

 

Therefore, you must set something to allow cross-origin access to the WCF Service. As a result, Google has the following. The specific method is found. Run the following code:

 

<? 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>

 

Save it as clientaccesspolicy. XML in the root directory of WCF. In this way, cross-origin access is enabled.
