I know that you are using .NET, but have you walked through the Java
examples first? Just to make sure you understand how it should work.
Here is some info about the examples:

http://activemq.apache.org/examples.html

The examples are very simple and straightforward. The only change you
will need to make in order to send persistent messages is to use the
following command when sending:

$ ant producer -Ddurable=true

The ProducerTool class will pick up the durable property and mark the
messages as persistent when it sends them. This will allow you to shut
down ActiveMQ, start up ActiveMQ and still see the 2000 messages in
the queue.
