WCF.svc 工作但不是配置文件

Question

I am trying to use the configuration file to define endpoint and services information. I have a very simple code that contain OneWay service and a Duplex service. The OneWay worked when I haven't try to alter the configuration file.

Now, I want to use the configuration file to define both service.

Service1 contract name is IOneWayService and the Service2 contract name is ICallBackService .

Both have implemented code in their concrete respective classes name OneWayService.svc.cs and CallBackService.svc.cs .

The configuration file at this moment look like that:

<configuration>
   <system.web>
      <compilation debug="true" targetFramework="4.0" />
   </system.web>
   <system.serviceModel>
      <serviceHostingEnvironment  multipleSiteBindingsEnabled="true">
         <serviceActivations>
            <add relativeAddress="OneWayService.svc" service="TestingWcf.OneWayService"/>
            <add relativeAddress="CallBackService.svc" service="TestingWcf.CallBackService"/>
         </serviceActivations>
      </serviceHostingEnvironment>
      <services>
         <service name="TestingWcf.OneWayService">
            <endpoint address="http://localhost:60847/One"
              binding="wsHttpBinding"
              contract="IOneWayService" />
         </service>
         <service name="TestingWcf.CallBackService">
            <endpoint address="http://localhost:60847/Two"
               binding="wsHttpBinding"
               contract="IDuplexService" />
         </service>
      </services>
      <behaviors>
         <serviceBehaviors>
            <behavior>
               <serviceMetadata httpGetEnabled="true"/>
               <serviceDebug includeExceptionDetailInFaults="false"/>
            </behavior>
         </serviceBehaviors>
      </behaviors>
   </system.serviceModel>
   <system.webServer>
      <modules runAllManagedModulesForAllRequests="true"/>
   </system.webServer>
</configuration>

I always have this error when trying to execute the OneWayService via this url: http://localhost:60847/OneWayService.svc

The contract name 'IOneWayService' could not be found in the list of contracts implemented by the service 'OneWayService'.

Anybody have an idea why?

Edit

I have removed the multipleSiteBindingsEnabled= true from the servinceHostingEnvironment tag and in the contract added the namespace and I could runt the OneWayService.

Also, the Duplex cannot be bound to the wsHttpBinding . I had to change it to NetTcpBinding . But, I had an other error with the Duplex:

Configuration binding extension 'system.serviceModel/bindings/NetTcpBinding' could not be found. Verify that this binding extension is properly registered in system.serviceModel/extensions/bindingExtensions and that it is spelled correctly.

From this point, I am lost again.

Edit 2

I did an error in the binding name. I had a capital letter for NetTcpBinding and it does require a lowercase: netTcpBinding . However, it's still not working, now I have:

The protocol 'net.tcp' is not supported. >.< !!!

Answer 1

OK, that explains it - Visual Studio by default uses the built-in Cassini web server (unless you've already switched to using IIS Express ) - and that server doesn't support anything but plain http.

Cassini doesn't support net.tcp and anything like that.

You will need to start using a separate IIS virtual directory and first enable all the necessary support stuff (in the Add/remove Windows Features dialog)
