該解決方案使用的是"silverlight導航應用程序+Oracle數據庫+WebService服務”

新建silverlight項目GH，同時會自動添加一個GH.Web,在GH.Web中添加"web 服務"，同時需要添加兩個XML文件用于解決跨域問題：

第一個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>

第二個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中添加一個文件夾：Model，用于存放實體類，然后添加"服務引用"：GH_ServiceReference
