  Hi, 

  I have Following Code in my app.config file 

  <?xml version="1.0" encoding="utf-8" ?>
  <configuration>
    <system.serviceModel>
      <behaviors>
        <serviceBehaviors>
          <behavior name="common">
            <serviceMetadata httpGetBinding="true" />
            <serviceDebug includeExceptionDetailInFaults="true"/>
          </behavior>
        </serviceBehaviors>
      </behaviors>
      <services>
        <service name="AddOneService1.AddOne" behaviorConfiguration="common" >
          <endpoint address="" binding="netTcpBinding" contract="AddOneService1.IAddOne">
          </endpoint>
          <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
          <host>
            <baseAddresses>
              <add baseAddress="net.tcp://localhost:10001" />
              <add baseAddress="http://localhost:10002"/>
            </baseAddresses>
          </host>
        </service>
      </services>
      <bindings>
       
      </bindings>
    </system.serviceModel>
  </configuration>

  and Getting error 

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

  And I have Made an interface and a class to implement Simplest Service using a Tutorial

  so Please Somebody let me know where I am wrong

  My Interface Code is 

  namespace AddOneService1
  {
      [ServiceContract]
      interface IAddOne
      {
         [OperationContract]
          int AddOne();
      }
  }

  And other Class is 

  namespace AddOneService1
  {
      class AddOne:IAddOne
      {
          int i = 0;
          int IAddOne.AddOne()
          {
              return i + 1;
          }
      }
  }

  And In my Main I am doing This thing 

   class Program
      {
          static void Main(string[] args)
          {
              
              ServiceHost host = new ServiceHost(typeof(AddOne));
              host.Open();
              Console.WriteLine("Service is Runnig... click enter to Close");
              Console.Read();
              host.Close();
  
          }
      }

  Hope to replied in answered sense aSAP

  Hi qqaadir,

  According to my experience, the issue comes from this( httpGetBinding="true"), httpGetBinding is a string that specifies the type of the binding that will be used for metadata retrieval via HTTP GET. This setting is optional. If it is not specified, the default bindings will be used. You most likely don't need to set that way, as the default should be fine.

  If you want to publish service metadata for retrieval using an HTTP/Get request, here you need set httpGetEnabled="true".

  Here is the documentation for the serviceMetadata node.

  Best Regards,
