我在.Net 4.0上有一个WCF Rest服务，当使用我的本地IIS 7.5时，这项服务运行良好。但我有一个虚拟主机软件包，当我向他们发布服务时收到一个应用程序错误，详细说明错误类型。以前我在.Net 4.0上发布了其他种类的WCF服务，这没关系。部署该服务的公司是Arvixe，我已联系他们的支持，他们告诉我将处理程序添加到我的web.config。但这不再有效。
这是我的web.config文件
<validation validateIntegratedModeConfiguration="false"/>
<modules runAllManagedModulesForAllRequests="true">
<add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</modules>
<handlers>
<!-- Make sure we can use this handler for any URL because we're using ReST. The default is
for it to be used only for .svc -->
<remove name="svc-Integrated-4.0" />
<add name="svc-Integrated-4.0" path="*" verb="*" type="System.ServiceModel.Activation.ServiceHttpHandlerFactory, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />

当我在我的wcf服务上调用操作时，这是我的跟踪日志！

在不知道你得到什么错误的情况下，建议任何事都很困难。我启用了WCF跟踪来进一步解决问题， http://msdn.microsoft.com/en-us/library/ms733025.aspx
