Windows Service中托管的WCF服务上的404错误

Question

I am trying to create a WCF service hostsed in windows service and I'm testing locally before I deploy to a server.

Created and installed the service ok and I can run the service just fine.

When I try to add a reference either though Visual studio or using WCFTestClient I get the following error.

Error: Cannot obtain Metadata from http://localhost/ServiceModelSamples/service If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address. For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error URI: http://localhost/ServiceModelSamples/service Metadata contains a reference that cannot be resolved:' http://localhost/ServiceModelSamples/service '. There was no endpoint listening at http://localhost/ServiceModelSamples/service that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. The remote server returned an error: (404) Not Found. HTTP GET Error
URI: http://localhost/ServiceModelSamples/service There was an error downloading ' http://localhost/ServiceModelSamples/service '.
The request failed with HTTP status 404: Not Found.

here is my app.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
  <service behaviorConfiguration="CalculatorServiceBehavior" name="Microsoft.ServiceModel.Samples.CalculatorService">
    <endpoint address="" binding="basicHttpBinding" contract="Microsoft.ServiceModel.Samples.ICalculator" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />        
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8000/ServiceModelSamples/service" />
      </baseAddresses>
    </host>
  </service>
</services>
<bindings>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="CalculatorServiceBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>        
  </serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>

As you can see its a slight modification to the tutorial found on msdn for hosting a WCF service in a Windows Service.

I have tried reaserching this but haven't found much or most of the issues seem related to IIS hosting.

UPDATE

After adding the port number as suggested by venerik, the error has now changed to the following.

Answer 1

You should connect your client (like WcfTestClient) to http://localhost:8000/ServiceModelSamples/service . The error says you are trying to connect to http://localhost/ServiceModelSamples/service without the port, that is.

I assume you have IIS running at localhost? That's why the error also says The remote server returned an error: (404) Not Found. The IIS server is listening at port 80 and cannot find ServiceModelSamples/service and thus returns 404.

The problem for me was the Service Name was not set in the service properties so I set this and also ensured the installer service name matched. Also set it to a LocalSystem Account. Not sure if that had any affect but it was set as NetworkService
