Configuration evaluation context not found warning on WCF trace

Question

I have a set of WCF services hosted on a .NET 4 application. I manually create the ServiceHost class and start listening on TCP port. All works as expected but in the WCF trace on the server side I get the warning below.

Configuration evaluation context not found.

XML trace follows:

<E2ETraceEvent xmlns="http://schemas.microsoft.com/2004/06/E2ETraceEvent"&gt;
<System xmlns="http://schemas.microsoft.com/2004/06/windows/eventlog/system"&gt;

<TraceRecord xmlns="http://schemas.microsoft.com/2004/10/E2ETraceEvent/TraceRecord" Severity="Warning">

<Description>Configuration evaluation context not found.</Description>
<AppDomain>Server.Console.vshost.exe</AppDomain>
</TraceRecord>
</DataItem>
</TraceData>
</ApplicationData>
</E2ETraceEvent>

Any idea about the reason of the warning?

Thanks

Did you take a look at that MSDN blog: Missing Binding Extensions?

The evaluation context not found error (or in traces with the identifier System.ServiceModel.EvaluationContextNotFound) is generally caused by using a configuration element defined in a library that is not included in the application’s configuration as an extension.
