C# WCF服务405方法不允许异常

我正在VisualStudio2008中编写一个WCF服务，该服务将托管在Windows2008标准服务器上

我已经在IIS7中创建了一个新的网站，它有自己针对ASP.NET 2.0的应用程序。我向服务器角色添加了.NET3.0Framework功能。我已经完成了涉及*.svc扩展和aspnet_isapi模块的所有步骤。我已经运行了“ServiceModelReg-r”并重新启动了IIS以及服务器本身

我的项目针对.NETFramework 3.5进行构建。我的解决方案将项目引用为使用服务器Web目录的UNC路径的网站。该项目构建时没有错误，我可以在我的客户端项目（在我的Win XP开发虚拟机上）中成功地向我的WCF服务添加服务引用。我的客户端项目生成并运行，但在服务方法（CheckDatabaseConnection）调用期间引发异常。My web.config和服务类附在下面，后面是客户端应用程序。我完全没有主意了

好的，看起来我通过在web.config中添加一个identity元素解决了这个问题。奇怪的是，这并不是网上流传的答案之一，但我在看一篇几乎无关的文章时偶然发现了它。修复方法如下所示：

        <service behaviorConfiguration="ConnectivityBehavior" name="EDCO.Web.Services.Connectivity">
            <endpoint address="http://validurl.net/Connectivity.svc" binding="wsHttpBinding" contract="EDCO.Web.Services.IConnectivity">
                <identity>
                    <dns value="validurl.net" />
                </identity>
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
