它曾经让我的大脑也受到伤害.

It used to make my brain hurt too.

我发现我需要这个文件:

I figured out for my use I needed this file:

<?xml version="1.0" encoding="utf-8"?>
<access-policy>
  <cross-domain-access>
    <policy>
      <allow-from http-request-headers="SOAPAction">
        <domain uri="*"/>
      </allow-from>
      <grant-to>
        <resource path="/" include-subpaths="true"/>
      </grant-to>
    </policy>
  </cross-domain-access>
</access-policy>

命名为clientaccesspolicy.xml

named clientaccesspolicy.xml

诀窍是它必须位于您的网络服务器的根目录.也就是说，您需要能够浏览文件.在您的情况下位于:

The trick is that is has to be at the root of your web server. That being said you need to be able to browse the file. In your case located at:

http://localhost:8732/clientaccesspolicy.xml

如果你看不到文件，silverlight 总是会抱怨，男孩会尽可能地抱怨！

If you cannot see the file silverlight will always complain and boy does it complain whenever it can!

我应该指出我的策略文件没有限制，所以明智地使用它.

I should point out that my policy file is not restrictive, so use it wisely.
