Question

I’m new to WCF. I have made a simple self hosted service and added app.config but when I type address in the browser it is not showing me the service page that we get when we create our service http://localhost:8067/WCFService it is not displaying the service as it shows when we run service.

But when I try to add base service in public static void main instead of app.config it works fine m not getting yy?? Can anyone please help me?

Following is the app.config file manually added:

<configuration>     
   <system.serviceModel>     
      <services>     
         <service name="SelfHostedWCFService.WCFService">     
            <endpoint
                address="http://localhost:8067/WCFService"
                binding="wsHttpBinding"
                contract="SelfHostedWCFService.IWCFService">     
            </endpoint>     
         </service>     
      </services>     
   </system.serviceModel>     
</configuration> 

Following is the Program.cs:

static void Main(string[] args)     
{     
    ServiceHost host = new ServiceHost(typeof(SelfHostedWCFService.WCFService));
    host.Open();     
    Console.WriteLine("Server is Running...............");      
    Console.ReadLine();
}

Following is the interface file manually added:

namespace SelfHostedWCFService     
{      
    [ServiceContract]     
    interface IWCFService      
    {     
        [OperationContract]     
        int Add(int a, int b);      
        [OperationContract]     
        int Sub(int a, int b);      
        [OperationContract]     
        int Mul(int a, int b);
    }     
} 

Following is the service.cs file manually added:

namespace SelfHostedWCFService
{     
    class WCFService:IWCFService     
    {     
         public int Add(int a, int b) { return (a + b); }      
         public int Sub(int a, int b) { return (a - b); }      
         public int Mul(int a, int b) { return (a * b); } 
    }     
} 

Is something wrong with my app.config or some other concept??

Answer 1

Everything seems ok at first glance – are you sure the service isn’t running??

Without any metadata being published, you cannot test the service using the WCF Test Client, nor can you generate a client-side proxy for it….

So I would recommend adding service metadata publishing to your service, and doing so, I was able to test that code of yours and it works just flawlessly.

To add metadata, change your config to:

<configuration>     
   <system.serviceModel>     
      <behaviors>
          <serviceBehaviors>
             <behavior name="Metadata">
                <serviceMetadata />
             </behavior>
          </serviceBehaviors>
      </behaviors>
      <services>     
         <service name="SelfHostedWCFService.WCFService" behaviorConfiguration="Metadata">     
            <endpoint
                address="http://localhost:8067/WCFService"
                binding="wsHttpBinding"
                contract="SelfHostedWCFService.IWCFService" />     
            <endpoint address="http://localhost:8067/WCFService/mex"
                      binding="mexHttpBinding" contract="IMetadataExchange" />     
         </service>     
      </services>     
   </system.serviceModel>     
</configuration> 

Even with this config, you won’t see any service page when navigation to the URL – but the service is up and running – just use the WCF Test Client and see for yourself!
