You create an XML Web service that uses the Trace class to output error messages, warning messages, and informational messages to a log file. The service uses a TraceSwitch object to filter the trace output.
The DisplayName property of the TraceSwitch object is “globalSwitch”. On a development computer, all trace output appears in the log file.
You move the service to a production computer. You must configure the production XML Web service to output only error messages to the log file.
What should you do?
