How to get the name of the called operation in IClientMessageInspector?

I applied IClientMessageInspectorto “intercept” an outgoing web service call in my application. Is it possible to find out which operation is called from within BeforeSendRequestand AfterReceiveReply?

There is a similar question, How to get the name of the called operation in WCF Message Inspector , which is for the server side (the party receiving the request). I tried to do something like this, for example.

    public object BeforeSendRequest(ref Message request, IClientChannel channel)
    {
        var v = OperationContext.Current.OutgoingMessageProperties["HttpOperationName"];
        return null;
    }

    public void AfterReceiveReply(ref Message reply, object correlationState)
    {
        var v = OperationContext.Current.OutgoingMessageProperties["HttpOperationName"];
    }

but during the outgoing request, it seems that OperationContext.Current is null, so I cannot use it. Any idea how to get it? Any idea how to do this cleanly (as opposed to, say, parse SOAP xml)?
