silverlight - 带有 WCF 的 Silverlight 中的跨域策略错误

Question

将我的 Silverlight 应用程序连接到我的 WCF 服务时出现以下错误。我将此 wcf 托管为自托管服务。

An error occurred while trying to make a request to URI 'http://lmr-hero/iSponsorWebSite/projectService.svc/basic'. 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.

此错误的可能原因是什么？

Answer 1

如果您的 Silverlight 应用程序未托管在与服务相同的域中，那么您需要将 clientaccesspolicy.xml 或 crossdomain.xml 文件放在托管服务的服务器上。
