MSMQ - message queuing has not been installed on this computer - msmq

Question

I have written a sample application to write to a public and private queues that are on dev server. I don't have the message queue installed on my local machine.
I am getting error: message queuing has not been installed on this computer.
Error is on this line:
MessageQueue.Exists(queueName)
Here is the full test code, all commented and not commented private and public queues are resulting in the same error. What am i doing wrong here?
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Messaging;
namespace MsmqTest
{
public partial class Form1 : Form
{
//#"DIRECT=OS:devbox01\PRIVATE$\PrivateQueueDev";
//#"DIRECT=TCP:192.168.6.102\PRIVATE$\PrivateQueueDev";
private const string QueueName = #"DIRECT=TCP:192.168.6.102\PRIVATE$\PrivateQueueDev";
//#"DIRECT=OS:devbox01\PublicQueueDev";
//#"DIRECT=TCP:192.168.6.102\PublicQueueDev";
private const string QueueNamePublic = #"DIRECT=TCP:192.168.6.102\PublicQueueDev";
public Form1()
{
InitializeComponent();
}
private void Write_Click(object sender, EventArgs e)
{
MessageQueue msgQ;
string msgText = String.Format("Message: {0}", DateTime.Now);
try
{
msgQ = GetQ(QueueNamePublic);
msgQ.Send(msgText);
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}
private void Read_Click(object sender, EventArgs e)
{
}
private MessageQueue GetQ(string queueName)
{
MessageQueue msgQ;
if(!MessageQueue.Exists(queueName))
{
try
{
msgQ = MessageQueue.Create(queueName);
}
catch (Exception ex)
{
throw new Exception("Error creating queue", ex);
}
}
else
{
try
{
msgQ = new MessageQueue(queueName);
}
catch (Exception ex)
{
throw new Exception("Error getting queue", ex);
}
}
return msgQ;
}
}
}

Answer 1

You need to install MSMQ on ALL machines which want to participate in the transmission and reception of messages. That includes sending machines such as your local machine in this instance.
The reason for this is because of the store-and-forward messaging pattern that MSMQ uses.
http://en.wikipedia.org/wiki/Store_and_forward
What is actually happening when you "send" a message to your server is:
The local queue manager writes the message to a local temporary queue.
The local queue manager connects to the remote queue manager.
The message is transmitted.
The remote queue manager writes the message to the remote queue.

Answer 2

Refactor out the MSMQ logic to a service and call the service from your code, passing the message. That way you only have to install MSMQ on the server.
