Question

I want my WCF service to log errors / operations, etc.

I have a very simple logging class but finding the directory to create / write to is returning a null reference exception:

    public static string Path()
    {
        return Path.GetDirectoryName
            (Assembly.GetEntryAssembly().Location);
    }

This works in say a console app but not WCF, perhaps there is a different convention?

Or alternatively are there any simple libraries for logging in WCF?

WCF has built-in message logging, following links should help you.
