要用到wcf了，看了下资料，在打开mex地址的时候显示400错误，不知道问题出在哪里，麻烦熟悉的朋友帮忙看看
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.web>
<compilation debug="true" defaultLanguage="c#" targetFramework="4.0" />
</system.web>
<system.serviceModel>

<service name="WcfService1.Service1">
<endpoint address="" binding="basicHttpBinding" contract="WcfService1.IService1" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>

<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false" />

</configuration>
http://localhost:8081/Service1.svc正常，http://localhost:8081/Service1.svc/mex就显示400错误
对WCF不熟悉，麻烦各位帮下忙，谢谢！
