I am currently making a WCF service and while I was developing the service

  • 0

I am currently making a WCF service and while I was developing the service acted like it should (Using Visual Studio Web Expres). I have a silverlight application who is consuming the service.

I wrote the WCF service in a class Library and is implemented by a ASP.NET Web Application. While I was using the Visual Studio ASP.NET Development Server the service was happy and gave me everything I asked for.

Now I implemented the service on an IIS 7 Server. And the service doesnt return what I ask for anymore. Instead in Chrome I get the following message:
The error through Chrome

But If I surf to the service url then the service say’s it is ready to rock and roll:
if I surf to the service

As you can see in the Error I get from Chrome is that the text the service returns is the Source code from that “surf to” page.

My Web.config service model:

<system.serviceModel>
      <bindings>
        <basicHttpBinding>
          <binding name="basicHttpBinding_OnlineCreatorServiceContract" closeTimeout="00:01:00"
                   openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                   maxBufferPoolSize="2147483647" maxBufferSize="2147483647"
                   maxReceivedMessageSize="2147483647">
            <readerQuotas maxDepth="2147483647"
                          maxStringContentLength="2147483647"
                          maxArrayLength="2147483647"
                          maxBytesPerRead="2147483647"
                          maxNameTableCharCount="2147483647" />
            <security mode="None" />
          </binding>

        </basicHttpBinding>
      </bindings>
      <services>
        <service behaviorConfiguration="OnlineCreatorServiceBehavior"
          name="OnlineCreator.ServiceLibrary.OrderDataService">
          <endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicHttpBinding_OnlineCreatorServiceContract"
            name="basicHttpBinding" contract="OnlineCreator.ServiceLibrary.IOrderDataService" />
          <endpoint address="mex" binding="mexHttpBinding" name="mexHttpBinding"
            contract="IMetadataExchange" />
        </service>
      </services>
        <behaviors>
            <endpointBehaviors>
                <behavior name="OnlineCreator.Web.OnlineCreatorServiceAspNetAjaxBehavior">
                    <enableWebScript />
                </behavior>
            </endpointBehaviors>
            <serviceBehaviors>
                <behavior name="OnlineCreatorServiceBehavior">
                    <serviceMetadata httpGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    </system.serviceModel>

And my ServiceReferences.ClientConfig:

<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="basicHttpBinding" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
                    <security mode="None" />
                </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://subdomain.domain.com/mapWithServiceInIt/OnlineCreatorService.svc"
                binding="basicHttpBinding" bindingConfiguration="basicHttpBinding"
                contract="OnlineCreatorService.IOrderDataService" name="basicHttpBinding" />
        </client>
    </system.serviceModel>
</configuration>

Because my service is on a subdomain I have used to following ClientAccessPolicy.xml:

<?xml version="1.0" encoding="utf-8" ?>
<access-policy>
  <cross-domain-access>
    <policy>
      <allow-from http-request-headers="*"> 
        <domain uri="*"/> 
      </allow-from> 
      <grant-to>
        <resource path="/" include-subpaths="true"/>
      </grant-to>
    </policy>
  </cross-domain-access>
</access-policy>

As you can see this can’t be the problem, but for completeness sake I have putted it here.

This is my first WCF service and it worked perfectly till I putted it on the IIS server. Does anyone has a clue why I get this error and how to fix it?

    After I have dug deeper in WCF and IIS I found out that you need to activate WCF on the server. And that is quite the process. To do it right I cleared my current site on IIS to have a fresh start and then followed to following pages to get the WCF to work:

    http://edinkapic.blogspot.com/2009/02/talking-to-wcf-service-from-silverlight.html

    I made a very simpel HelloWorld service to test everything and as soon as it all worked I ported it to my service. That first gave me an exception. But that was soon fixed because the connection strings weren’t set right.
