Question

I am trying to set up a WCF Service but I’m having a few problems. The service works and loads the wsdl page when I type in

www.mydomain.com/Service1.svc

However when I use

www.mydomain.com/Service1.svc/

or try to use any of the get methods I get

The resource cannot be found.

Description: HTTP 404.

My web.config file is as follows

<?xml version="1.0"?>
<configuration>

  <system.webServer>
    <handlers>
      <remove name="PageHandlerFactory-ISAPI-4.0"/>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

The Service.svc file is as follows :

namespace RestService
{
    public class Service1 : IService1
    {
        public bool LoginUser( string Username, string password )
        {
            return true;
        }
    }
}

and the IService.cs is as follows:

namespace RestService
{
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        [WebInvoke(Method = "GET",
            ResponseFormat = WebMessageFormat.Json,
            //BodyStyle = WebMessageBodyStyle.Wrapped,
            UriTemplate = "login/{username}/{password}")]
        bool LoginUser(string username, string password);
    }
 }

The pipeline mode on the server is “Integrated” if that helps. I’m not sure what IIS version my hosting provider (pipeten) uses but I think it’s 7.5 I have a feeling this has something to do with the URL validation however there is no option on my hosting to change this.

Okay turns out it was a simple mistake that I had made, I had missed out the . when adding the handler. Instead of path = “” it should have been path=”.“

<add name="ASP.NET-ISAPI-4.0-Wildcard"
         path=".*" verb="GET,HEAD,POST,DEBUG"
         modules="IsapiModule"
         scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll"
         preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
