下面的代码假设运行一个自托管的自定义身份验证WCF 服务，该服务需要向 Silverlight 4 客户端提供其服务（参见下面的代码）。
结果是即使 clientaccesspolicy.xml 在浏览器中可见并且没有显示 SSL 错误，也会引发臭名昭著的 clientaccesspolicy Security Error 通信异常。未命中 clientaccesspolicy.xml 断点。
我意识到我只需要指定条目，但我已经尝试了使用 clientaccesspolicy.xml 的各种游戏，但都不起作用。
感谢您的帮助
1) 这是服务的 app.config 和代码：

2）我们在本地机器的 MY 容器中有一个 CA 签名的 SSL 证书，并使用了 netsh
netsh http add sslcert ipport=0.0.0.0:9999 certhash=aabbcc_thumbprint
appid={my_app_id_guid} clientcertnegotiation=enable
以上成功执行并且主机正确加载并允许创建新的silverlight项目。
3）silverlight项目是一个刚刚添加服务引用和以下代码的新silverlight项目：
namespace SilverlightApplication1
{
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
ServiceReference1.Service1Client c = new ServiceReference1.Service1Client();
c.ClientCredentials.UserName.UserName = "1";
c.ClientCredentials.UserName.Password = "1";
c.GetPrivateInfoCompleted += new EventHandler<ServiceReference1.GetPrivateInfoCompletedEventArgs>(c_GetPrivateInfoCompleted);
c.GetPrivateInfoAsync();
}
void c_GetPrivateInfoCompleted(object sender, ServiceReference1.GetPrivateInfoCompletedEventArgs e)
{
if (e.Error == null)
{
this.Content = new TextBlock() { Text = e.Result };
}
else
{
this.Content = new TextBlock() { Text = e.Error.GetBaseException().Message };
}
}
}
}
4）这是生成的ServiceReferences.ClientConfig
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IService1" maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647">
<security mode="TransportWithMessageCredential" />
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="https://(TheAddress)/MyCustomValidationService"
