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">
    <System xmlns="http://schemas.microsoft.com/2004/06/windows/eventlog/system">

    </System>
    <ApplicationData>
        <TraceData>
            <DataItem>
                <TraceRecord xmlns="http://schemas.microsoft.com/2004/10/E2ETraceEvent/TraceRecord" Severity="Warning">
                    <TraceIdentifier>http://msdn.microsoft.com/it-IT/library/System.ServiceModel.EvaluationContextNotFound.aspx</TraceIdentifier>
                    <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.
