.net 无法访问Visual Studio正在发布的WCF Web服务

更新：我不知道这是否有助于任何人诊断此问题，但wsdl的终点是：

http://localhost:8523/Temp/WebService.svc/WebService.svc

这是错误的，我尝试手动更改端点以删除末尾的额外位，但它仍然返回404

/更新

我正在使用WCF处理web服务，当我运行VS2010调试器时，会收到以下错误消息：

目标程序集不包含服务类型。您可能需要调整此程序集的代码访问安全策略

我在网上找到的解决方案是，我应该将[ServiceContract]添加到界面中，但它已经存在了

我还看到有人说我必须从csproj文件中删除标记，但这样做会使项目成为类库而不是web服务

但是我的浏览器会打开一个目录列表，通过单击.svc文件，然后单击指向.svc？wsdl的链接，我可以导航到容器生成的wsdl

如果我尝试从应用程序或WCF service Tester中点击服务，我会得到一个404异常，我将一个测试应用程序打包在一起，下面是它给我的异常：

有人能告诉我我可能做错了什么吗？如果我在IIS或VS2010中的内置Web服务器中托管，我会遇到类似的问题。配置中的服务标签是错误的。应该是以下内容：

<service name="namespace.WebService" behaviorConfiguration="WebServiceBehaviour">
        <endpoint address="WebService.svc"
                  binding="wsHttpBinding"
                  bindingConfiguration="DefaultWSBinding"
                  name="WSEndPoint"
                  contract="namespace.IWebService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange"
                  bindingConfiguration="mexHttpBinding"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost/Temp/"/>
          </baseAddresses>
        </host>
      </service>

---

service元素中的name值和endpoint元素中的contract值应该是完全限定的。

这是我清理Web.config以删除对客户端的引用的结果，service name和endpoint contract都有名称空间。对不起，你在IIS上托管吗？项目中是否有.svc文件。您的意思是配置中的服务名称和端点约定被指定为完全限定名称吗？我已尝试在IIS中托管，在Cassini Visual Studio中，我有一个实现[ServiceContract]的.svc文件我将尝试在一个干净的解决方案中重新加载代码，看看这是否有效……您是否能够浏览到服务页面并在IE中查看wsdl？还可以尝试使用Fiddler调用web服务并监视请求-响应，看看它是如何运行的？我可以使用service_Name.svc？wsdl浏览到wsdl，我已经将它加载到SOAP UI中，该UI将为服务生成存根，但当我尝试执行任何方法时，它只是404。
