how to get WCF WS client to log requests and responses by app.config tracing?

Question

My app.config is below. However there i nothing in C:\temp\xxx\ folder. What I'm missing? This is 1st time i ever try this so I don't know anything about this. There is nothing in code. I think something is tried to be done because if I have the response formatted (line feeds and tabs) the response results in exception. I use soapUI mock service to return response.

Answer 1

My WS client is built to WSClient.dll which is used from MainProgram.exe. In build my App.config of the WSClient project was translated to WSClient.dll.config. I thought that this was ok. However it must be copied to MainProgram.exe.config and it works.

Your config looks ok, please note you have to restart the service after adding logs. Make sure that the service has all required permissions for creating log files

here is my version of a config file
