           Summary: Cannot configure ConsoleTraceListener to use standard
                    error through configuration
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.4.x
          Platform: Other
        OS/Version: RHEL 4
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: System

Description of Problem:

You cannot configure the ConsoleTraceListener to use standard error though
configuration file. It should be possible to do this with a config file like
the following

    <trace autoflush="false" indentsize="4">
        <add name="Console"

where initializeData="true" indicates to use standard error. This works fine
with Microsoft .NET.

Steps to reproduce the problem:
1. Create simple program that just use System.Diagnostic.Trace
2. Compile making sure to enable trace (or add defined TRACE to program)
3. Create config file for exe with above content
4. Run program

Actual Results:

Unhandled Exception: System.Configuration.ConfigurationException: Couldn't find
constructor for class System.Diagnostics.ConsoleTraceListener

  at System.Diagnostics.Trace.WriteLine (System.String message) [0x00000] 
  at Test.Main (System.String[] args) [0x00000] 

Expected Results:

Program should print Trace output to standard error

How often does this happen?
