该解决方案使用的是"silverlight导航应用程序+Oracle数据库+WebService服务”

新建silverlight项目GH，同时会自动添加一个GH.Web,在GH.Web中添加"web 服务"，同时需要添加两个XML文件用于解决跨域问题：

第一个XML文件：clientaccesspolicy.xml：

<?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>

第二个XML文件：crossdomain.xml:

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />
<allow-http-request-headers-from domain="*" headers="*" />
</cross-domain-policy>

在GH中添加一个文件夹：Model，用于存放实体类，然后添加"服务引用"：GH_ServiceReference
