更新：我不知道这是否有助于任何人诊断此问题，但wsdl的结束点为：
http://localhost:8523/Temp/WebService.svc/WebService.svc
哪个错了，我尝试手动更改端点以删除末尾的额外位，但仍然会返回404
/更新
我正在使用WCF处理Web服务，当我运行VS2010调试器时，我收到以下错误消息：
目标程序集不包含任何服务类型。您可能需要调整此程序集的代码访问安全性策略。
我在网上找到的解决方案说我应该在接口上添加[ServiceContract]，但它已经存在。
我也看到有人说我必须从csproj文件中删除标签，但这样做会使项目成为类库而不是Web服务。
但是我的浏览器打开了一个目录列表，我可以通过点击.svc文件然后点击指向.svc的链接导航到容器生成的wsdl？wsdl
如果我尝试从应用程序或WCF服务测试程序中获取服务，我会得到404的异常，我将测试应用程序拼凑在一起，这是它给我的例外情况：
Sending Message: Make Call: InteractionId [rt], Destination [ert], ExternalReferenceId [ert], userIdentifier [ert] attachedData [rt]
System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at http://localhost:8523/WebService.svc?wsdl that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---> System.Net.WebException: The remote server returned an error: (404) Not Found.

有人可以告诉我，我可能做错了吗？如果我在IIS或VS2010中的内置网络服务器中托管
，我会遇到类似的问题答案 0 :(得分：0)
配置中的服务标签错误。本来应该是这样的：
<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。
