Logging the caller ip in a asmx web service using NLog
One possible change would be to use object initializer to set up the properties:

var logInfo = new LogEventInfo(level, logger.Name, message)
{
    Properties = { { "method", method }, { "calling_ip", calling_ip } }
};


But I'm not sure this actually improves the code much, especially since using this syntax this way is uncommon, so it can be confusing.
