Description of Problem:

The ConsoleTraceListener is double printing when used in conjunction with
TraceSwitch. Below are two simple examples that cause this to happen. 

In the first case the double printing happens when I add the "Info" level to
the TraceSwitch constructor options. 

In the second case the double printing occurs if I access the Warning member of
the switch before I do a write.If I do a write before I access Warning than it
does not double print.


Steps to reproduce the problem:

1. Compile and run the following program

#define TRACE

public class Test
{
    public static void Main(string[] args)
    {
        System.Diagnostics.TraceSwitch myswitch = new
System.Diagnostics.TraceSwitch("myswitch", "Test Switch", "Info");
        System.Diagnostics.Trace.WriteLine("Here is a message");
    }
}


2. Compile and run the following program

#define TRACE

public class Test
{
    public static void Main(string[] args)
    {
        System.Diagnostics.TraceSwitch myswitch = new
System.Diagnostics.TraceSwitch("myswitch", "Test Switch");
        bool warning = myswitch.TraceWarning;
        System.Diagnostics.Trace.WriteLine("Here is a message");
    }
}


Actual Results:

The message is printed twice.


Expected Results:

The message should only appear once.


How often does this happen? 

Always
