Help with WMI in windows services

As a fairly new .net developer I am looking for some help with WMI in VB.net on the .net 4.0 framework.

I will start with an overview of what I am trying to achieve. I have several windows services that I have written and I want to expose the work these services are doing to a management application for the operators to see what work is currently being done or whether the service is currently idle.

After some googling I came across the concept of WMI which seemed to cater for what I was trying to achieve perfectly.

I think I have got my head round coding the things I want to expose from the windows service. What I am having trouble with is how I can fire an event of some sort that the management application can see to let it know that something has changed and update its UI with the information.

After a lot more googling I am getting a bit stuck and hence the question.

I would be happy to know if there are better alternatives to WMI that I should be using.

I hope this is enough information to enable someone to point me in the right direction.

Thanks in advance,

Dave
