Problems using FileStream in a seperate AppDomain

[mathboy2]

Hey,

I've created a very simple test app to try and fix a problem I'm
having. Basically I'm trying to log to a text file from a class in a
seperate app domain that I've created. When I first create the
AppDomain I'm able to log. However, I have the requirement that I'll
have to tear down the AppDomain and then load it back up again. When I
do this I no longer get any logging.

Note that the first thing I thought of is that the file was somehow not
being release, but I've modified the code below to create with a
different filename each time the AppDomain is loaded with no success.

Any help would be appreciated!

***** Text Logger *****

using System;
using System.IO;
using System.Text;

namespace prairieFyre.IQRealtimeClient
{
public class TestLogger : MarshalByRefObject
{
StreamWriter m_fileWriter;

public TestLogger()
{
FileStream stream = new FileStream("TestLogger.txt",
FileMode.Append, FileAccess.Write, FileShare.ReadWrite);
m_fileWriter = new StreamWriter(stream);

}

public void WriteText()
{
m_fileWriter.WriteLine("THIS IS MY TEST!");
m_fileWriter.Flush();
}
}
}
******* Test App *******

(this loads the AppDomain)
m_realtimeAppDomain = AppDomain.CreateDomain("Realtime AppDomain");
TestLogger testLogger =
(TestLogger)m_realtimeAppDomain.CreateInstanceAndU nwrap("RealtimeClient",
"prairieFyre.IQRealtimeClient.TestLogger");

testLogger.WriteText();
testLogger.WriteText();

(This is how I unload the AppDomain)
AppDomain.Unload(m_realtimeAppDomain);
m_realtimeClient = null;
