Host WCF on IIs

Question

Hi all

I have this error when I try to host my WCF serivce

There was an error downloading 'http://localhost/8900/CRTS'.
The request failed with HTTP status 404: Not Found.
Metadata contains a reference that cannot be resolved: 'http://localhost/8900/CRTS'.
There was no endpoint listening at http://localhost/8900/CRTS 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.
If the service is defined in the current solution, try building the solution and adding the service reference again.

and my App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <system.serviceModel>
  <services>
   <service behaviorConfiguration="CartBehaviors" name="ShoppingCartService.CartServiceImpl">
    <endpoint address=""
         binding="wsHttpBinding" bindingConfiguration=""
     name="wsHttpBindingCT" contract="ShoppingCartService.IShoppingCart" />
    <endpoint address=""
         binding="mexHttpBinding"
         contract="IMetadataExchange" />


    <host>
     <baseAddresses>
      <add baseAddress="http://localhost/8900/CRTS" />
     </baseAddresses>
    </host>
   </service>
  </services>
  <behaviors>
   <serviceBehaviors>
    <behavior name="CartBehaviors" >
     <serviceMetadata httpGetEnabled="true" />
    </behavior>
   </serviceBehaviors>
  </behaviors>
 </system.serviceModel>

 <connectionStrings>
  <add name="XYZEVEDSN" connectionString="server=localhost; integrated security = true;database=XYZEveDB"/>
 </connectionStrings>
</configuration>
