WCF Service error on IIS with metadata - wcf

Question

I'm trying to publish a service to IIS, it builds and runs OK on the ASP.NET dev server. When running in IIS I can get to the metadata by navigating to the service or by adding service reference in Visual Studio. But when I call a method from my client app it crashes with a internal server error. So I went to the Event Log and found this:
WebHost failed to process a request.
Sender Information: System.ServiceModel.Activation.HostedHttpRequestAsyncResult/8810861
Exception: System.Web.HttpException (0x80004005): There was no channel actively listening at 'http://mysite.net/soundhubservice.svc/$metadata'. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening. ---> System.ServiceModel.EndpointNotFoundException: There was no channel actively listening at 'http://mysite.net/soundhubservice.svc/$metadata'. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening.

My Web.Config looks something like this:
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service name="SoundHub.Services.SoundHubService" behaviorConfiguration="StreamingServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="http://localhost/SoundHubServive"/>
</baseAddresses>
</host>
<endpoint address="service" binding="basicHttpBinding" bindingConfiguration="httpBuffering" contract="SoundHub.Services.ISoundHubService"/>
<endpoint address="stream" binding="basicHttpBinding" bindingConfiguration="HttpStreaming" contract="SoundHub.Services.ISoundHubStreamService"/>
<!--<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />-->
</service>
</services>
<bindings>
<basicHttpBinding>
<binding name="HttpStreaming" maxReceivedMessageSize="67108864" transferMode="Streamed"/>
<binding name="httpBuffering" transferMode="Buffered" />
</basicHttpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="StreamingServiceBehavior">
<serviceMetadata httpGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="False"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
Tried several combinations of settings I found while searching online but nothing helped, always the same error.
Thanks

Answer 1

I had this problem when one of the objects I returned contained an enumeration; turns out it couldn't figure out how to serialize it.
If that's your problem, try returning the int value of the enum (or a string value) and cast it back to the enum on the client side.
