Trouble reading from Memory Mapped File
===

I am trying to implement a Memory Mapped File within my application (specifically a Windows Service), and then use a C# form to read from MMF the service writes to. Unfortunately i cannot seem to get the form to read anything from the MMF, more importantly it seems that the form never finds the MMF created by the Service. Below are code snippets that outline what im doing, can anyone see what I am doing wrong or be able to point me in a better direction?

Service :

    private MemoryMappedFile mmf = MemoryMappedFile.CreateOrOpen("AuditStream", 1024 * 1024);
    private Mutex mutex = new Mutex(false, "MyMutex");

    byte[] msg = new byte[1];
    var view = mmf.CreateViewStream(0, 1);
    byte[] rmsg = new byte[1];

    for (int i = 0; i < 400; i++)
    {
         mutex.WaitOne();
         for (int j = 0; j < msg.Length; j++)
         {
              msg[j] = (byte)i;
         }

         view.Position = 0;
         view.Write(msg, 0, bufferSize);

         //the next 3 lines verify that i wrote to the mmf and can potentially read from it
         //These are just for testing
         view.Position = 0;
         view.Read(rmsg, 0, 1);
         Log.Error("Finished MMF", rmsg[0].ToString());

         mutex.ReleaseMutex();
     }
   

Form:

    private MemoryMappedFile mmf;
    private Mutex mutex;
    Thread t = new Thread(MmfMonitor);
    t.Start();

    private void MmfMonitor()
        {

            byte[] message = new byte[1];
            while(!quit)
            {
                try
                {
                    **mmf = MemoryMappedFile.OpenExisting("AuditStream");**
                    mutex = Mutex.OpenExisting("MyMutex");
                    var view = mmf.CreateViewStream(0, 1);

                    mutex.WaitOne();
                    view.Position = 0;
                    view.Read(message, 0, 1);
                    Invoke(new UpdateLabelCallback(UpdateLabel), message[0].ToString());
                    mutex.ReleaseMutex();
                }catch(FileNotFoundException)
                {
                    **//The AuditStream MMF is never found, and therefore doesnt every see the proper values**
                }
            }
        }

Additionally, while the service is 'Running', the MMF should always have a handle and shouldnt get collected by the garbage collector;
