How to write SCOM 2007 R2 probes in .NET?

Question

I am trying to extend SCOM 2007 to run the .NET code that I wrote. This code can query the status of the internal system and return its status.

I am new to SCOM and can find ways to achieve this with an action probe that executes my code as a command. It can then display some results that should be interpreted using a powershell script for something non-trivial.

Does anyone know how best to do this? Any useful links would be greatly appreciated!

Thanks!
