The management API's are also available through COM, that doesn't mean you
can't use C# to access them, simply create a interop assembly from the
automation server dll (msclus.dll) and use the API's from C#.
However, the "automation server API's" don't support notifications, a much
better "managed" option is to use System.Management namespace classes and
the WMI cluster classes MSCluster_XXXX to build cluster management
applications using C#.

I can post a sample of the latter if you are interested.
