Configure Service Model for WCF

Question

I have a very basic webservice using WCF (C#, .NET 4.0), to return an hello message.

The deployment under IIS 7 and running it is ok, but when I do svcutil.exe http://localhost:4569/Service.svc?wsdl through the CMD to test the webservice I get:

the remote server returned an error: 415 cannot proccess the message because the content type 'aplication/soap+xml charset=utf8' was not the expected type 'text/xml charset=utf8'

When trying to add the service reference (to create a client) I get

An existing connection was forcibly closed by the remote host Metadata contains a reference that cannot be resolved: 'http://localhost:4569/Service.svc'. Content Type application/soap+xml; charset=utf-8 was not supported by service http://localhost:4569/Service.svc. The client and service bindings may be mismatched. The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..

I'm pretty sure that the problem is under my Web.config file:

    <configuration>
      <system.web>
        <compilation debug="true" targetFramework="4.0" />
      </system.web>
      <system.serviceModel>
<services>
         <service name="Service">
             <endpoint name="soap" 
                 address="http://localhost:4569/Service.svc" 
                 binding="basicHttpBinding" 
                 contract="IService" />
             <endpoint name="mex" address="mex" binding="mexHttpBinding" 
                       contract="IMetadataExchange" />
         </service>
         <behaviors>
            <serviceBehaviors>
               <behavior>
                  <serviceMetadata httpGetEnabled="true"/>
                  <serviceDebug includeExceptionDetailInFaults="false"/>
               </behavior>
            </serviceBehaviors>
</services>
         </behaviors>
         <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
      </system.serviceModel>
      <system.webServer>
        <modules runAllManagedModulesForAllRequests="true"/>
      </system.webServer>
    </configuration>

Anyway, here's my code:

IService.cs:

[ServiceContract]
public interface IService
{
    [OperationContract]
    string getMessage();
}

My service.cs has the method

public class Service : IService
{
    public string getMessage()
    {
        return "Ola servico";
    }
}

I really don't know what is happening, did some tests after some research but no success.

Service.svc

<%@ ServiceHost Language="C#" Debug="true" Service="Service" CodeBehind="~/App_Code/Service.cs" %>

You're not showing us the interesting (and important) parts of your config! The <services> section in <system.serviceModel> on the server side and the contents of the *.svc file! Please add those - otherwise we're left guessing at best.... — marc_s
is that the entire config file? are the services, bindings and endpoints defined in code? — MLT
The error message would indicate that you're mixing SOAP and REST. It seems you want to retrieve a WSDL, yet it would appear as if you're using the REST binding (webHttpBinding) .... — marc_s
when you say 'running it is ok' do you mean in the browser and have you tried connecting to it via wcftestclient? also, and this may be a stupid question, but is your getMessage() implementing the service contract? — MLT

You have no service and endpoint defined in your config. Try adding

<services>
  <service name="Service"> <!-- name should match the name in your .svc file (if you open it with a text editor) -->
    <endpoint name="soap" address="" binding="basicHttpBinding" contract="IService" />
    <endpoint name="mex" address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
