This sounds more like a discussion question than a specific issue (usually bugs).

It sounds like your WCF service is being hosted inside IIS, which current directory is the directory of the IIS executable. There is a token {AppData} that you can use to write logs into the ~/App_Data directory. This is safer than writing into the application root folder, e.g. it is protected from downloads.

This change is documented on the RollingFileTraceListener page (, however it is not listed on the XML page -- although both use the same underlying writer and it should work for both.

Try using initializeData="{AppData}/logfile.txt" (or initializeData="{AppData}/logfile.svclog"), and let us know how you go.
