Turning tracing off via app.config

I'm trying to use System.Diagnostics to do some very basic logging. I figure I'd use what's in the box rather than taking on an extra dependency like Log4Net or EntLib.

I'm all set up, tracing is working wonderfully. Code snippet:

Trace.TraceInformation("Hello World")

App.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.diagnostics>
    <trace autoflush="true" indentsize="4">
      <listeners>
        <add name="TraceListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="Trace.log" traceOutputOptions="DateTime" />
        <remove name="Default" />
      </listeners>
    </trace>
  </system.diagnostics>
</configuration>

and my little "Hello World" shows nicely up in my Trace.log file. But now I'd like to switch OFF tracing, so I dig into MSDN and find How to: Configure Trace Switches . I add the <switches> element, and now my app.config looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.diagnostics>
    <trace autoflush="true" indentsize="4">
      <listeners>
        <add name="TraceListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="Trace.log" traceOutputOptions="DateTime" />
        <remove name="Default" />
      </listeners>
    </trace>
    <switches>
      <add name="Data" value="0" />
    </switches>
  </system.diagnostics>
</configuration>

The value="0" should turn off tracing - at least if you then follow How to: Create and Initialize Trace Switches, which tells you to add this line of code
