C# Restful WCF HTTP错误404.0-在IIS中托管时未找到

我正在创建一个简单的WCF服务，它返回如下内容

{LoginResult:WCF A的您好}

我使用blow from浏览器访问服务

当从VisualStudio本地运行时，它在IIS Express中运行得非常好。但当部署到远程IIS时，我收到HTTP错误404.0-找不到。如果访问，我可以查看我的服务默认页面

。这是我的Web.config

<?xml version="1.0"?>

问题在于address元素。应该是

<endpoint address="" binding="webHttpBinding" contract="MyService.IService1"  behaviorConfiguration="webhttpbehavior">

<endpoint address="" binding="webHttpBinding" contract="MyService.IService1"  behaviorConfiguration="webhttpbehavior">
