Installing .NET services

[Inquisitor]

I have a service I've written in C#, which has its own installation code to go with it. What's the best way to go about installing the service with a third party installer like NSIS? I've looked on the NSIS wiki, but the only installers there don't make use of the installation info I've provided for my service, so when I look in the SCM, there's no description of the service and the name just defaults to the name of the executable

Any help appreciated
